text: I can't imagine a time in the future when no one needs them anymore becasuse I'm sure no one wants to wait until one of the Taxis are free. I'm the type of person thart doesn't have the patients to wait until a taxi to come pick me up. What if you want to have a latenight drive and taxis drivers don't allow that? What if someone ges irrritated because the taxi driver has a very monotone voice? What if hacker hacks into someone driveless car and kidnaps them by driving their smart car to a whole new destination.
