I think it depends on what you mean by big challenges. City driving is maybe the easiest 80% of driving. There’s a long tail of odd challenges you run into in less controlled environments, and I’d call that the biggest challenge.

I think city driving is the worst — people popping out from nowhere, roads that shouldn’t be but are because they have always been. Suburban and highways seem easiest.

In the hills of LA you have sharp blind corners where people have installed public fisheye mirrors to help you see around, then you have crazy people in Hollywood throwing furniture in front of your car, and non-stop traffic and people passing on the wrong side of the road between blocks even when there is a median, school kids and crossing guards, emergency vehicles trying to through and people doing otherwise illegal things to help get out of the way…

I'm an avoid motorcyclist and have followed additional safety courses. These placed 90% of all accidents in cities. What do you mean by city driving being the easiest?

		In a city, you'll never have to worry about the "road" you're supposed to follow being a dirt track that barely looks different than the muddy fields on either side. In a city (especially in SoCal and the American Southwest, which is, AIUI, where all the self-driving cars are today), you can be nearly certain that the various mapping companies have accurately plotted the roads and destinations, and if you're trying to get to a popular Finger Lakes winery, you won't be directed down a limited-use seasonal road that's entirely covered in ice. In a city, you can be pretty well guaranteed that there are speed limit signs anywhere the speed limit actually changes. Just off the top of my head, as someone who's lived 40 years in the rural Northeast.

Wouldn’t ice trucking be in that long tail? I mean, ya, there are lot of niche cases that companies like Waymo haven’t worked on yet, but…the money is in the cities so that’s where they start. Interstate trucking might come next, ice trucking might be one of the last use cases covered.

Anyways we’ve gone from “this won’t happen in our lifetime!” to “it doesn’t handle X niche use case yet.”

		There are self driving trucking companies.
