While people discuss the possibility of eliminating fossil fuel cars, let's not ignore the danger of a disastrous side effect: total surveillance of people's travel. This threatens democracy (see https://gnu.org/philosophy/surveillance-vs-democracy.html).
The danger is that we will have to use a driverless version of what Uber is now.
Uber requires customers to run a program that is proprietary and secret, controlled solely by Uber. Not surprisingly, the program is malware -- it even tracks users' movements before and after the ride.
(See https://gnu.org/philosophy/free-software-even-more-important.html for this general issue.)
Uber also requires users to identify themselves. You can hail a real taxi on the street and pay cash, but there is no way to call an Uber car or pay for the ride without identifying oneself.
Uber does many other nasty things -- see stallman.org/uber.html. However, either of those two wrongs by itself is an injustice I won't stand for as a passenger.
Uber is worse than merely an unjust alternative. It runs at a loss, aiming to kill off the other alternatives. If it succeeds, how then will we avoid being tracked in all our movements?
Driverless cars can be implemented in a way that respects our freedom. It's not even difficult, not really. But that's not what governments and companies will do if left to themselves. To get that, we have to campaign for that.
