>1. HD vehicles will be second-class citizens, not allowed in road-train HOV lanes where the automated vehicles are travelling bumper to bumper at 120 km/h

and most of the rest is a good illustration of how the big corporations think, or how they usually write the specs for programmers. They see the bulk of the problem THEY are facing, and hope to cover 90% of the cases by 3-4 options, and then just remove all other options because they aren't profitable. Having been a special case for eleven years, I've seen this too many times. Dang, I even had to sign to be owner of daughter's car, because it had to be someone with a driver's license. She just wanted to buy a car and then learn to drive - which is impossible in the US.

Now imagine all the uses of cars which are not covered by the areas where HOV lanes exist. Driving off the road to that house in the mountain, or to the river to pull someone's boat out, or to a camping site near the lake. Driving away in an emergency when all that roadside telemetry may be without power. Driving crazy because thugs in a HD vehicle are chasing you and shooting. Driving very slowly because you want to read an anouncement on a sign. Disrespecting an obviously wrong road sign. Etc, etc. I'm sure they can't possibly think of all of that.

OTOH, if they be segregated, nice. All the bad drivers should be confined to these train chain roads, so they can text at will, fix their makeup and generally let us drive on the rest of the roads, good riddance.
