The interesting challenges on a interstate are pretty similar as the usual challenges of autonomous vehicles, so what happens if there is a construction site, or if there are people on the road. (But you have to deal with that at a lot higher speeds.)
And Ars had a very interesting article on the validation of self-driving cars, the thing is humans are rather good at driving, to the tune of 10^8 km per fatal accident, so you need really huge statistics to validate self driving cars. I suspect that if you want to show that your autonomous truck is as save as a human truck driver, then you acquire another factor of 2 in the kilometers needed. (Actually I seem to remember that it is about a factor of 5, but that is entirely unsourced.)

- ghaff 10y agoIt's a big step to go from interstate autopilots to having no human in the loop end-to-end. If autopilot systems improve safety and/or are autonomous enough that drivers can sleep and thereby make fewer stops, they'll certainly make sense. However, it may also make economic sense to keep a human on board to handle unanticipated issues or last mile tasks that may be harder to automate.
- yk 10y agoIf the driver can sleep, than the car needs to handle everything that can happen on the interstate, including deer or people on the road. So I would guess that a interstate autopilot has the same difficult challenges, but 'simpler' things like navigation may be easier. Basically my argument boils down to, it is easier to drive on an interstate on average, but for autonomous vehicles we are not interested in average and the hard challenges are similar to hard challenges for a fully autonomous car.

You don't get a lot of jaywalkers or bicycles doing unexpected things. Nor negotiation of left-hand turns, etc. What you do have is events happening at higher speeds but handling the car in front jamming on its brakes is probably easier in general for a machine that's always paying perfect attention. As a result, I do expect to see autonomous systems on limited access highways before I see them in a busy city. That said, I fully agree that once you have full automation you can't depend on human backup that can take over quickly. Whether or not people are supposed to, they will doze off, read, text, etc.--even more than they do today.
- wmeredith 10y agoI would think dealing with the SAME challenges simply at higher speeds would mean automation wins every time.
