Safe follow distance isn't an evolutionarily-stable strategy. The number of accidents avoided by people following it is more than offset (at least psychologically in the minds of the drivers) by the perception that people are constantly cutting you off if you adhere to it. Since punishments for failing to adhere to it are few and far between, drivers get sloppy.
It's the sort of thing you could, however, program into a robot and expect the robot to adhere to it.

I've often wondered what people will initially do when being driven around by a robot. How anxious will it make them feel, not to give up control, but to see a robot driving "so slowly". Not going 10 over, letting other drivers in when possible, always slowing to keep a safe distance, not passing aggressively if someone is going a few miles under, etc.
In the far future, i suspect people will be so used to being driven that they won't care how fast they're going. They can browse, work, surf, do whatever they like. But the first wave of drivers being driven.. it's going to be interesting to see how people respond to it.
And that's not even accounting for the drivers who still driving, but seeing robots on the road. I bet they'll always want to pass robots asap.
I think that you were fooled by the news coverage. It's only on non-divided highways that the new restriction applies, and there was already a restriction to speed limit + 5mph on such roads. On divided highways, you can set any speed up to 90mph.
The freight vehicle or bus is pretty similar to a robot today. They have much stiffer penalties for speeding, much more difficulty changing lanes (including often being banned from passing lanes), and much more difficulty stopping. Experienced truckers and bus drivers do all of these things.
