I'm going to assume the founder of a self-driving truck company knows what he's talking about.
But at the same time, I have a hard time reconciling that with the fact that I sat in a car that drove itself all around San Francisco, dealing with a ton of edge cases.
Maybe we won't get to a 100% drive-anywhere-you-want-car in 10 years, but to be fair, a lot of humans aren't capable of driving a car anywhere either.
There are a lot of LA drivers who can't drive in snow, for example. I was one of them, until I got practice, and even then, I'm not that safe at it.
I think as long as we set the bar at "drive anywhere a car can go with 100% safety" we will never reach that bar.
But if the bar is at "drive as well as a human in most of the places humans drive", well, I've already seen a car that can do that.
