And I doubt that the personal automobil is going extinct anyhow. You can use internal combustion machines with hydrogenium (synthesized e.g. from water with wind or nuclear energy), biodiesel, natural gas, ... and you can have cars based on compressed air and electric cars (again with plenty of possible renewable sources). I simply can't see the terrible energy scarcity, that would be required to end the car.

For sure people will drive less, and the average weight of the cars will be reduced. But that isn't the end of the car.
