3 is still pretty new. I&#x27;m not poor by any stretch of the imagination, but I bought a 9 year old car. It is still going fine (now 12 years old).<p>Given that adaptive cruise control is still an expensive luxury, I can&#x27;t see fully self-driving cars coming to the poor any time soon.<p>That said, if we ever do get totally autonomous cars, you&#x27;ll probably be able to get a driverless taxi for very little cost without owning a car yourself.
