I've talked before about Traffic by Tom Vanderbilt. It's an interesting journey into the world of traffic psychology and engineering, and has one chapter on robocars. That chapter was based on seeing Junior at Stanford, and things have come a long way since then.

Yesterday I attended the conference on the legal implications of robocars put on by Santa Clara University Law Review. It was a well done conference, with some real content from a varied group of regulators and legal scholars, a sign of how real the robocar world has become.

Frequently these days I will see some shocking statistic reported:

A new robocar project named "Quasper" has emergence in France from the IRSEEM Esigelec lab and IFSTTAR. This vehicle uses a commercial actuator robot to control the wheel and pedals for drive-by-wire, and features a variety of typical sensors, though it only has a couple of smaller SICK LIDARSs rather than a high resolution LIDAR like the Velodyne used by many other projects. Their work is fairly basic for now.

Back to wishlists on credit cards: Every year, for tax time, I go over my downloaded credit card records and I classify them into categories. I could just try to divide out the business and personal expenses (which I handle by having credit cards for business only and for personal only) but I try to do a bit more categorization, and from time to time there's a reason I don't follow the strict rule about what card to use.

Over the years I have come to the maxim that "Everything should be as secure as is easy to use, and no more secure" to steal a theme from Einstein. One of my peeves has been the many companies who, feeling that E-mail is insecure, instead send you an E-mail that tells you you have an E-mail if you would only log onto their web site (often one you rarely log into) with the password you set up 2 years ago to read it.

Like many, I go to a lot of conferences and events. And many of those events have decided that they should give everybody a bag. Most commonly it's a canvas laptop sized bag, though sometimes it's a backpack and at cheaper events just a tote. Some of the bags are cheap, some are quite nice. Some come with just the logo of the event on them, and others come festooned with many logos from sponsors who bought a space on the bag.

Almost all credit cards will let you download transactions. Many will e-mail you a balance or payment reminder once a month, or a warning if your balance goes above a certain amount. And I've seen a small number that will e-mail you on every transaction.

But does anybody have a smart notification system which I can set, allowing me to be comfortable that there is no misuse of my card without filling my mailbox?

Spokesmen for the MPAA, RIAA and several other content industry companies recently issued a statement of support for the new "Stop Airline Piracy Act" or SAPA, now before congress.

This time of year I do a lot of online shopping, and my bell rings with many deliveries. But today and tomorrow, not Saturday. The post office comes Saturday but has announced it wants to stop doing that to save money. They do need to save money, but this is the wrong approach. I think the time has come for Saturday and Sunday delivery to be the norm for UPS, Fedex and the rest.

There are a large number of constitutional amendments being proposed to reverse the effects of the recent US Supreme Court decision in Citizens United v. Federal Election Commission.

Here the court held that Citizens United, a group which had produced an anti-Hilary Clinton documentary, had the right to run ads promoting their documentary and its anti-Clinton message. It had been held at the lower court that because the documentary and thus the ads advocated against a candidate, they were restricted under campaign finance rules. Earlier, however, the court had held earlier that it was OK for Michael Moore to run ads for Fahrenheit 9/11, his movie which strongly advocated against re-electing George W. Bush. The court could not find the fine line between these that the lower court had held, but the result was a decision that has people very scared because it strips most restrictions on campaigning by groups and in particular corporations. Corporations have most of the money, and money equals influence in elections.

Most attempts at campaign finance reform and control have run into a constitutional wall. That's because when people talk about freedom of speech, it's hard to deny that political speech is the most sacred, most protected of the forms of speech being safeguarded by the 1st amendment. Rules that try to say, "You can't use your money to get out the message that you like or hate a candidate" are hard to reconcile with the 1st amendment. The court has made that more clear and so the only answer is an amendment, many feel.

It seems like that should not be hard. After all, the court only ruled 5-4, and partisan lines were involved. Yet in the dissent, it seems clear to me that the dissenters don't so much claim that political speech is not being abridged by the campaign finance rules, but rather that the consequences of allowing big money interests to dominate the political debate are so grave that it would be folly to allow it, almost regardless of what the bill of rights says. The courts have kept saying that campaign finance reform efforts don't survive first amendment tests, and the conclusion many have come to is that CFR is so vital that we must weaken the 1st amendment to get it.

With all the power of an amendment to play with, I have found most of the proposed amendments disappointing and disturbing. Amendments should be crystal clear, but I find many of the proposals to be muddy when viewed in the context of the 1st amendment, even though as later amendments they have the right to supersede it.

The problem is this: When they wrote that the freedom of the press should not be abridged, they were talking about the big press. They really meant organizations like the New York Times and Fox News. If those don't have freedom of the press, nobody does. And these are corporations. Until very recently it wasn't really possible to put out your political views to the masses on your terms unless you were a media corporation, or paid a media corporation to do it for you. The internet is changing that but the change is not yet complete.

Many of the amendments state that they do not abridge freedom of the press. But what does that mean? If the New York Times or Fox News wish to use their corporate money to endorse or condemn a candidate -- as they usually do -- is that something we could dare let the government restrict? Would we allow the NYT to do it in their newspaper, but not in other means, such as buying ads in another newspaper, should they wish to do so? Is the Fox News to be defined as something different from Citizens United?

I'm hard pressed to reconcile freedom of the press and the removal of the ability of corporations (including media ones) from using money to put out a political message. What I fear as that to do so requires that the law -- nay, the constitution -- try to define what is being "press" and what is not. This is something we've been afraid to do in every other context, and something I and my associates have fought to prevent, as lawsuits have tried to declare that bloggers, for example, were not mainstream press and thus did not have the same freedom of the press as the big boys.

Earlier I wrote about desires for the next generation of DSLR camera and a number of readers wrote back that they wanted to be able to swap the sensor in their camera, most notably so they could put in a B&W sensor with no colour filter mask on it. This would give you better B&W photos and triple your light gathering ability, though for now only astronomers are keen enough on this to justify filterless cameras.

As expected, there's more news from the Tokyo auto show, which is well known for strange concept cars.

First there is the Toyota Fun Vii

Nissan has announced a new version of their Pivo concept car. The Pivo 3 here's a story with a video offers 4 wheel steering and automatic parking, including a claimed functionality for automated valet parking. In the AVP case, the car requires a special parking lot, though it is not said what changes are needed. A few years ago the Stanford team demonstrated Junior 3 which could valet park in a lot to which it had a map, and which had no civilian pedestrians.

In contrast to the optimism I usually present here, and last week's article about a self-driving Mercedes just a year away it's worth noting this interview with various BMW folks where they provide a much more cautious timeline of at least a decade. Part of their concern comes from the use of computer vision systems.

For the first time, a car company has put a date on shipment of a car with self-driving ability.

According to British site Auto Express, Mercedes has revealed that their 2013 S-class will feature self-driving. Not clear if there is an official company press release, though the company has been talking about such features, as have many other companies. Realize that the 2013 model year is just a year away.

I shoot with the Canon 5d Mark II. While officially not a pro camera, the reality is that a large fraction of professional photographers use this camera rather than the Eos-1D cameras which are faster but much bulkier and in some ways even inferior to the 5D. But it's been out a long time now, and everybody is wondering when its successor will come and what features it will have.

Each increment in the DSLR world has been quite dramatic over the last decade. There's always been a big increase in resolution with the new generation, but now at 22 megapixels there's less call for that. While there are lenses that deliver more than 22 megapixels sharply, they are usually quite expensive, and while nobody would turn down 50mp for free, there just wouldn't be nearly as much benefit from it than the last doubling. Here's a look at features that might come, or at least be wished for.

Better Pixels

More pixels may not be important, but everybody wants better pixels.

• Low noise / higher ISO: The 5D2 astounded us with ISO 3200 shots that aren't very noisy. Unlike megapixels, there is almost no limit to how high we would like ISO to go at low noise levels. Let's hope we see 12,500 or more at low noise, plus even 50,000 noisy. Due to physics, smaller pixels have higher noise, so this is another reason not to increase the megapixel count.
• 3 colour: The value of full 3-colour samples at every pixel has been overstated in the past. The reason is that Bayer interpolation is actually quite good, and almost every photographer would rather have 18 million bayer pixels over 6 million full RGB pixels. It's not even a contest. As we start maxing out our megapixels to match our lenses, this is one way to get more out of a picture. But if it means smaller pixels, it causes noise. The Foveon approach which stacked the 3 pixels would be OK here -- finally. But I don't expect this to be very likely.
• Higher dynamic range: How about 16 bits per pixel, or even 24? HDR photography is cool but difficult. But nobody doesn't want more range, if only for the ability to change exposure decisions after the fact and bring out those shadows or highlights. Automatic HDR in the camera would be nice but it's no substitute for try high-range pixels.

Video & Audio

Due to the high quality video in the 5D2, many professional videographers now use it. Last week Canon announced new high-end video cameras aimed at that market, so they may not focus on improvements in this area. If they do, people might like to see things like 60 frame video, ability to focus while shooting, higher ISO, and 4K video.

Last week, new studies came back on the California High Speed Rail project. They have raised the estimated cost to $99 billion, and dropped the ridership estimate to 36.8 million and $5.5 billion in annual revenue. Note that only around 20 million people currently fly the SF to LA corridor -- they expect to not just capture most of those but large numbers of central valley trips.

Congestion on the roads has a variety of sources. These include accidents of course, reductions in road capacity, irrational human driving behaviours and others, but most of all you get congestion when more cars are trying to use a road than it has capacity for.

That's why the two main success stories in congestion today are metering lights and downtown congestion charging. Metering lights limit how fast cars can enter the highway, so that you don't overload it and traffic flows smoothly. By waiting a bit at the metering light you get a fast ride once on the highway. Sometimes though, especially when the other factors like accidents come into play, things still gum up.

Now that more and more cars are connected (by virtue just of the smartphone the driver carries if nothing else) the potential will open up for something else in congestion -- finding ways to encourage drivers to leave a congested road.
