Yup. And much, much more. Which is why this could NEVER happen within the next decade. There needs to be (at minimum, just few things that come to mind)
- A secure driver database. That includes BOTH secure onboard data PLUS secure real-time updates that must be sent in near "real-time" over the air to all those cars on the road
- Guaranteed transmission bandwidth to assure all the info and updates for all those cars are guaranteed to make it over the airwaves.
- Area Coverage. Points 2 and 3 almost certainly mean infrastructure investment and build-out including several earth orbiting satellites plus "urban canyon" coverage. (Urban canyons for areas of downtown sky scrapers, tunnels, and other forms of interference and blockage, etc)
- Minimum safety standards set by NHTSA (National Highway Traffic Safety). No auto manufacturer would attempt take on liability issues before minimum standards for accuracy, reliability, etc. are set by the US DOT
- New laws from Congress regarding liability and meeting minimum safety standards for these new vehicles (and Congress, of course, can't get anything done)
- Also consider it takes 3-5 years of assembly line planning and preparation before an automaker can build out the current year car model
And those are just things off the top of my head. So no way this happens within a decade!
