So mud and dirt and dust and oil and antifreeze and all kinds of garbage spray on the roads covers all parts of a car. Some people never wash their car if they don't want to. What happens with these sensors? Can they detect physical interference? Will they refuse to let an assist mode of any kind activate if there is a malfunctioning sensor? What kind of self-diagnostic do they run, how often and how fail-proof is it?

  And when those break down and the owner doesn't fix it? Self driving cars will require regular and stringent inspections of functionality, otherwise it's a time bomb.

    Private individuals owning self-driving vehicles won't really be a thing in the longer term, it doesn't make economic sense. There are countless advantages to having a company or local government run and maintain a fleet.

      > it doesn't make economic sense It does, in the other parts of the world, where there are cars being made that exist outside of the luxury market. You can still get a Nissan Versa for $16k. Adjusted for inflation, that's only $7k, in 1990, which is cheaper than a Ford Escort from 1990, and 35% more horsepower. The problem is that people's standards are ridiculous.

    This seems fairly trivial. * Since safety regulations will be required for this, include a built in self test, with a refusal to engage self driving until the test/sensors are deemed safe enough. * Race cars use a spool of plastic film over their cameras, so a clean window is always ready. That's on option. There's the standard wiper. If you look around next time you're out, you'll see that most cars are very clean. So, I think this would be a non issue for most people. * Since the self test requirements may become more stringent over the years, cars that can't comply with the latest requirements can have an anual/semi annual verification, like we do now for emissions of older cars. Maybe as part of the standard, thresholds for the self test will need to be adjustable, to keep them in the "safe" range, and trigger earlier checks/cleaning. * You have to compare all of this to having a human behind the wheel.

      I am not sure if you live in the USA but we have dozens of states without any car inspection at all. In my city alone there are hundreds if not thousands of cars and trucks that drive around without mufflers or exhaust bypass, headlights broken or off at night. Tesla Model3 is one of the most popular selling cars now and that's just a hop and skip away from someone hacking the self-driving to always being on and selling it for cheap like the exhaust bypass hack that's been done to tens of thousands of trucks on the road today. https://www.thedrive.com/news/inside-the-epas-messy-war-on-dirty-diesel-trucks https://www.thedrive.com/news/inside-the-epas-messy-war-on-d...

Both of my cars have some level of ADAS systems on them. Both have ways to have sprayers clean cameras or have the cameras in the path of the standard wipers. When they cannot sense well enough they will disallow activating their ADAS features. What happens when the windshield gets to coated in junk that the driver can't drive?
