One of the car companies is quoted as having caused no serious injuries or deaths, so it seems like the 90 incidents number only includes those. Unfortunately the article doesn't question those numbers or explain what is counted, which is very poor journalism. I don't understand how they can write about the protesters' motivations without asking how many moving violations those cars have caused, or at least mention that this number is unknown.

If the numbers indeed don't count the times where they block traffic, stop for no reason or block emergency vehicles where they need to wait for the company to send someone out to the car, then AV's could be far worse than human drivers, not only in the number of incidents but also in the total delays they cause. At least a human driver can be removed from the car so that someone more competent can take over and resolve the situation quickly. And a human generally doesn't just stop in a lane and refuse to move out of the way for a very long time.

Another bonus: a human can just remove a cone from the hood and continue driving.

And they will definitely be better than people. Just them being able to communicate with each other, even locally, can remove the need for traffic lights already.
