In my article about how advertising won't pay for robotaxi rides I hinted at one surprise source of the problem. Maybe advertising can never be very valuable.

Right now, the most popular type of advertising, makes about 60 cents for one hour of TV watching. This is with what's known as a $20 CPM (cost per thousand.) Thats 2 cents per ad shown to a person, and an hour of TV has around 15 minutes of ads, or 30 spots.

Yesterday I examined some of the details released by the NTSB about the Uber fatality. Now I want to dig deeper with speculation as to the why. Of course, speculation is risky, though I can claim a pretty good track record. When I outlined various possible causes of the incident just after it, I put 4 at the top. I figured that only one might be true, but it turned out that two were (Misclassification as a bicycle, and the car wanting to stop but being unable to actuate the brakes) though I did not suspect Uber deliberately blocked the car from doing hard stops. So I'll try my luck at speculating again.

The NTSB has released its preliminary report on the fatality involving the Uber prototype self driving car. The NTSB does not attempt to assign blame, but there are some damning facts in the report.

Most of the world was wowed by the Google Duplex demo, where their system was able to cold-call a hairdresser and make an appointment with her, with the hairdresser unaware she was talking to an AI. The system included human speech mannerisms and the ability to respond to the random phrases the hairdresser through back.

Most of the press reported a research report from UBS securities claiming Waymo is now worth $75B to Google because it is poised to dominate the robotaxi business. In addition to this, it claimed that business would be $1.2 trillion by 2030, with an additional $472 billion for "in car monetization." (Total Google revenue was $110 billion in 2017.)

Everybody loves a good secret conspiracy theory. Here's mine for North Korea. Of course, it is probably not true. But is it impossible?

Kim Jong-Un is a tyrant, perhaps the last of his kind, and living in the new modern era. With this Swiss education, unfettered access to the internet and a love of foreign media, what sort of mindset might he hold? We don't know a lot.

Even if you are not in California, you may have heard of Proposition 13 the ballot measure which changed property tax rules.

It was part of a tax revolt, and it changed how the value of your real estate is calculated for property taxes. As California property started zooming up in price, there were people who owned homes but had minimal incomes. They were facing growing tax bills even though they had not realized the gains on their house. Some were being forced out of houses they had lived in for decades, the story went.

The wake of Tesla's incident has caused a lot more questions about the concept of testing prototype robocars on public roads supervised by "safety drivers." Is it putting the public at risk for corporate benefit? Are you a guinea pig in somebody's experiment against your will? Is it safe enough? Is there another way?

I'm off in June to do some speaking in Europe. I'm flying to Milan in business class from San Francisco for $2,800 on UA and Air Canada, which is about the lowest price I've ever seen for biz class to Europe in summer on the major airlines. The coach fare can be as low as $600 for those not able to splurge. Let me tell you how to use these fares, even if it's not Italy you wish to visit.

As a customer, the pricing plans of the car rental companies baffle me. I mean I understand about the goals for differential pricing -- finding ways to charge richer customers more money -- but still, I find it very frustrating, and I am curious why one of the majors doesn't have the courage to break out of the current pricing models and win over customers.

Like many, I have been highly interested in understanding the rift in US and global politics that has resulted in the rise of Trump, LePen, Ford and Brexit.

While I run mostly in left/urban/secular/keen circles, I try as often as possible to talk to people in other circles to understand their view. My own politics match neither side, which gives me some extra perspective. However, living in left circles, I have encountered more of their terms.

There was a lot of buzz yesterday about publication by a team at CSAIL and MIT about their research on driving without a map.

The newsletter "The Information" has reported a leak from Uber about their fatal accident. You can read the article but it is behind a very expensive paywall. The relevant quote:

A crash today with a Waymo van is getting attention coming in the same area just a short time after the Uber fatality, but Waymo will not be assigned fault -- the driver of the car that hit the Waymo van veered out of his lane into oncoming traffic because of somebody else who was incurring on the intersection. Only minor injuries, but higher energy than prior crashes for Waymo.

At teams around the world attempt to build safe robocar systems, one key asset has stood out as a big differentiator -- experience. For a company to be willing to certify their vehicle as safe, it needs experience with all the strange circumstances that it might encounter driving the roads.

Various sources suggest that just 3-5% of inmates in prison are there because of a trial. The vast bulk of them got there due to a guilty plea, part of a plea agreement.

This seems shocking, but in fact it is to be expected. Trials are long and expensive and risky. The vast majority of commercial disputes are settled out of court.

The primary purpose of the city is transportation. Sure, we share infrastructure like sewers and power lines, but the real reason we live in dense cities is so we can have a short travel time to the things in our lives, be they jobs, friends, shopping or anything else.

Sometimes that trip is a walking one, and indeed only the dense city allows walking trips to be short and also interesting. The rest of the trips involve some technology, from the bicycle to the car to the train. All that is about to change.

A huge opportunity awaits a young social media company that is poised to take advantage of the fall of Facebook (and Twitter). Is somebody out there ready to carry the ball and make it happen. It probably has to be somebody already with most of this done, or even operating.

The NHTSA/SAE "levels" of robocars are not just incorrect. I now believe they are contributing to an attitude towards their "level 2" autopilots that plays a small, but real role in the recent Tesla fatalities.

You've probably heard the catchword in the bitcoin/crytpocurrency world of "HODL!" Based on somebody's typo, it is an encouragement to hold on to your bitcoins rather than sell them as the price ramps up to crazy levels. If you're a true believer, you will HODL. Don't cave in to the temptation and pressure to sell (SLEL?) but be sure to HODL. (Previously I wrote about the issues which occur should Bitcoin's price actually stabilize.
