Probably not if you factor in depreciation on an expensive self-driving electric car. Looks like SF to Chicago is at least 2000 miles.

(Which also makes me wonder how you can do that trip in 20 hours. Speeding indeed :)

I can only assume as autonomous travel increases and incidents decrease, the speed limit would increase. Obviously battery technology still has a ways to go to be able to last more than a couple hundred miles running 100 MPH+

Speed limits depend more on the road (banking in corners, surface conditions, imperfections) and the car (what happens to the vehicle if an accident does happen) than the drivers, so I wouldn't expect major increases in speed limits.

I doubt that or else you wouldn't see the same stretch, and grade of road get two different speed limits depending on what side of the state border that you are on.

Additionally, on the intrastate highways, the speed limits are set by local districts so local districts who like making money will often change their speed limit for any highways that go near by them so they can speed trap people.

I dunno, In newer cars I have some sense of dislocation like I'm not really going as fast as the speedometer says.

Clearly, I'm mistaken on the exact times.

Last time I drove it took me four days, but I only drove 8 hours a day and took a long way around.
