>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.

I dreamed up the road train example just to prime the pump, there will no doubt be many others.

As for "all the uses of cars..." etc. - that doesn't address the real issue(s), namely:

- Human drivers don't get those "outliers" right all the time either. The majority are not as good as they think they are e.g. https://en.wikipedia.org/wiki/Illusory_superiority#Driving_ability . Human driving screwups are so legion and legendary that we've become inured, only the most egregious cases are considered noteworthy

- In a rational world SD vehicles don't have to "think of all of that" or be perfect, they just have to be better than humans. Even with no roadside telemetry at all SD vehicles should at some point be able to outperform humans. Think multifrequency radar/infrared or other sensors in dark, foggy conditions etc. GPS navigation can still work even if all street lights are out during a power failure. But of course it's not a rational world, to be accepted SD vehicles will have to have a failure rate a fraction of HD vehicles (10% ? 5% ? 1% ? - that's an interesting social question). Still, at some point it will tip, and people will trust SD cars more than HD.

Just because some arguments for SD cars sound "corporate" doesn't mean they're necessarily wrong. It's going to take the skills and resources of large companies to effect major change. I'd suggest Tesla is an example of the smallest size of company that can take on this challenge. With their Model 3 they have a huge risk and opportunity, they've truly grabbed the tiger by the tail.

I was going to ignore the "thugs with guns" scenario (however Hollywood that sounds [or maybe things are different in Serbia ;-)?]). But that sort of leads back to Jos' earlier comments about loss of autonomy. One possible way to address that would be to have an emergency/"Mayday" function. If a vehicle occupant declares a mayday that would allow the vehicle to ignore local ordinances in the interest of occupant safety. It might be subject to post-incident review. There would need to be some limits to that e.g. I can't load my vehicle with 1/2 a ton of explosives, declare a mayday then drive into the middle of a presidential motorcade. Might need some hierarchy of authority or trust to handle those situations.
