LIDARS for robocars are everywhere at CES

I'm back from CES and my first report concerns the trends in the LIDAR industry I saw from the 43 LIDAR companies exhibiting there. I talked to most of them. Those trends include lowered cost, more robust instruments and scores of paths to victory. There is also much more attention on LIDAR for the ADAS market. Bosch even said it would make a LIDAR, but said nothing about it.

Robocars 2019 Year In Review

Here is a summary of the Robocar stories from 2019 that were the most significant. It was actually not a year of very big change. Waymo is still the distant leader, in spite of having slipped a bit on their goals. I talk about the trough of the hype cycle and the challenges going ahead for the 2020s. If you skipped most of my coverage in the year, these are the selected ones to read.

California regulations are no cause for panic but they show "gasoline thinking"

If you read stories that California just put in new regulations that will change all the per-minute chargers and Tesla superchargers, don't worry, the changes are not that big and don't apply to chargers for some time. But it is worth examining how the regulations, such as they are, exhibit 20th century "gasoline thinking" by imagining that the same rules that apply to gas pumps should apply to electric charging stations. See about it in my Forbes site article:

The Dems may have chosen the two wrong articles of impeachment

One has to be impressed in a perverse way at the fact that no Republican broke ranks on Donald Trump in the impeachment vote. Some even defended their votes with passion. I've often felt that since we know several of them loathe Trump that they were just acting out of party loyalty and a sense of self-preservation within their party.

But I start to wonder that some serious number of them, and their voters, don't think Trump's actions are that big a deal. Here's why:

EV fast charging connector battles and standards wars might be OK

It's a common lament that because there are so many EV charging plugs (including the 4 fast-charging systems -- Tesla, Chademo, US-CCS and Euro-CCS) that we need a universal standard, so that we can get the goal everybody wants of being able to charge any car anywhere.

Trolleys, Risk and Consequences: A Model For Understanding Robocar Morality

One of the most contentious issues in robocars are the moral issues involved in testing and deploying them. We hope they will prevent many crashes and save many lives, but know that due to imperfection, they also create a risk of causing other crashes, both in deployment, and during deployment. People regularly wonder if they should be out there tested on city streets, or ever deployed. Even with numbers that are perhaps the most overwhelmingly positive from a utilitarian standpoint, we remain uncertain.

How to save a lot of money when installing electric vehicle charging in your home

Often when you attempt to install an EV charging station in an older home, you find that the old 100 amp service on your panel is not enough, and the electrician may quote a very large price to replace the panel and upgrade the service.

There are ways to avoid paying thousands of dollars by putting in a modestly smaller circuit, and you may find it charges you just fine. Here is a guide to how to get away with less than a 50 amp plug and save many thousands.

In car navigation needs to learn to shut up

I think driving navigation is a great thing, but the UI is all wrong. It needs to work to understand me, to see the routes I have driven with it 100 times, and only tell me when there is something unusual I need to know, not where to turn to get to my house (or telling me "You have arrived at your destination" at my driveway.) The ideal navigation system, on a commute, won't even say a word to me unless there is traffic that means I should not take my standard route. How do we make it smarter?

California Is Collecting the 2019 Robocar Disengagement Reports. It Should Stop

California is now collecting the 2019 "disengagement reports" for robocars, which always get lots of attention. But in fact, they are measuring the wrong thing -- it is the safety of testing they should measure in the public interest, not the quality of the prototypes -- and they are measuring it wrong, and pushing companies to do things that may be unsafe in order to meet their wrong and useless metric.

Battery, ICE, Hybrid: What About Temporary Mixes?

I was thinking about all the different variants of battery powered and hybrid cars, and thinking about the BMW i3 REX, which is a medium range PHEV that uses a small, cheap motorcycle engine to drive a generator. I think there might be two new types of semi-hybrid cars with this approach, so I wrote up a summary of all the types, and where the new modes fit it, particularly a plan to make cars with a receiver in which a temporary generator module can be placed.

EV Electric cost goes up 25%, nobody blinks, plus why your Uber isn't electric

Here are two recent articles on the economics of electric vehicles.

On Nov 1, PG&E, probably the most common power company for electric vehicle owners, raised the cost of their EV off-peak rate by about 25% in exchange for making the off-peak period last longer. Nobody even noticed, even though a 25% rise in gas prices would be a major calamity in the eyes of many. I look into that math and why nobody cared in:

FCC starts to take the DSRC spectrum back for unlicenced

The FCC has finally declared it intends to take 45mhz of the DSRC spectrum and make it unlicenced instead, though they are still leaving 20mhz for C-V2X (Qualcomm's LTE based replacement for DSRC that is mostly similar with 10mhz still to be figured out. Getting rid of DSRC and the silly idea of vehicle to vehicle communications is a good idea, but they should go even further -- and solve the V2V problem far better -- but making it all unlicenced and doing V2V in phones, not cars.

Traffic doesn't go up 85%, and we can solve congestion

A recently released tiny study from UC Berkeley gave 13 people personal chauffeurs for a week to see how their travel habits changed. They found their car miles going up 85%, but in most cases it was for silly reasons that would not actually happen. Still, miles will go up with robotaxis -- but congestion doesn't have to increase at all.

Daimler Makes Risky Bet Pulling Back From Robotaxi Business

Daimler's CEO has said they plan to "scale back" and "rightsize" their robotaxi efforts and focus on Trucking. Trucking is a good field for them, but this is a big bet.

Bet right and the company avoids wasting some money on being too early to the self driving game. Bet wrong and there may be no Daimler.

Cities stuck in last mile, Stupid Cities, Scooters and the future of Hydrogen

Two articles this week from 3 conferences I attended.

First look at How Cities are Stuck in the "last mile" and other observations from a conferences on cities and new mobility. I examine how scooter companies are working with cities, and how self-driving car tech is mapping cities by keeping the infrastructure dumb.

Recharging in 10 minutes is less exciting than you think

Lots of folks were forwarding a story about a battery lab at Penn State that has shown a battery that can be recharged in 10 minutes. This is good (and many other labs and companies have demonstrated other ways to do that. But my key reaction is that those who think it's a huge deal are still thinking of electric cars like gasoline cars that you fill up at filing stations. They aren't. With a recent EV, not on a road trip, you charge only at home while you sleep, which takes zero time. Fast charging is not of value there. An article about this can be found in
