Ever watched solo "cheaters" go by in the carpool lane and been angry? Turns out carpool lanes don't really work and often make congestion and throughput worse, which is why they are converting them to "HOT" (carpool+toll) lanes where they can, to let enough solo drivers in to properly use capacity.

Turns out carpool cheaters create a similar result, and if the fines and enforcement are tuned, they can pay a similar amount.

Over 60,000 EV charging stations have been installed in the US. But a huge number of them see fairly light use because they are not in the right place for the current generation of electric cars, and not for the coming self-driving ones.

At the Automated Vehicle Summit, and in may other places, one of the watchwords is "sharing." Everything is going to be great because robocar technology enables "sharing." Yet people use it to mean two different things -- taxi hailing and riding in groups -- and they don't really understand the real consequences of both.

I'm back from the AUVSI/TRB "Automated Vehicles Summit," this year in Orlando, Florida.

The opening session, kicked off by Chris Urmson of Aurora, was about current approaches to safety. In the various presentations, I noticed an evolution in thinking about safety, which I describe in this Forbes site article. We've moving away from incidents and miles and functional safety to operational safety and risk management.

It's not a big surprise, but Cruise has announced they will not meet their goal of deploying in 2019. Cruise says deploying in San Francisco is 40x harder than a place like Phoenix where Waymo is deploying, but that once they solve this harder problem, they will be the leader.

Is that the right strategy? I examine this in a new Forbes site article:

People are working hard to get robocars to handle public streets, but they also need to handle private parking lots for parking, pick-up and drop-off. Private lots have all sorts of strange rules, so a system is needed to make it easy to map them and make those maps and rules available to cars. I outline such a system in a new Forbes site article found here:

How Self Driving Cars will figure out Parking

GM's "Cruise" robocar unit is often cited as #2 behind Waymo. Some recent leaks of their internal metrics for progress paint a dim picture; that they aren't nearly as far along as they hoped, which does not bode well for the planned 2019 launch. In fact, they show as an order of magnitude behind where Google/Waymo was back in 2015.

Tomorrow, June 8, marks the 30th anniversary of my launch of ClariNet.com. In the 1980s, there was a policy forbidding commercial use of the internet backbone, but I wanted to do a business there and found a loophole and got the managers of NSFNet to agree, making ClariNet the first company created to use the internet as a platform, the common meaning of a "dot-com."

I've written about how to make Tesla Supercharging work, you try to have a meal while doing that. Here's a proposal to make that work much better: Be able to order food from participating restaurants while on the way to the charger, and have it all timed perfectly to either:

You've seen the hype and battles over 5G. You may also have seen claims that one of the most important reasons we need 5G is communication with robocars. While more bandwidth and lower latency are never bad things, it's a mistake to presume the cars are doing to depend on them, or that getting 5G is some sort of blocking factor.

I explain the (fairly low) bandwidth needs of cars in a new Forbes.com article:

Evidence mounts that sea level rise can't be avoided now, absent some miracle of geoengineering, and maybe not even with that. Even if you're one of those who insists human pollution isn't the cause, the planet is getting warmer, the ice sheets are melting at extreme rates.
