Cars cost much more than cameras (one or two zeroes more) so old cars are going to stay around for a longer time. The other problem is building the energy distribution network. The street road I'm looking at now is filled with parked cars and no recharge points. There is a gas station. Any of those cars can spend five minutes there and go on for hundreds of km. None of them could be recharged if they were electric. There is a car sharing service with electric cars in this city. They have their own recharge points. They drive their cars there at night. They use portable car batteries to move cars with completely empty batteries. My guess is that's going to take much more than five years to get to the point where people can be confident of being able to recharge their batteries anytime they need it. Some EU countries set the late 2030s as a target to stop selling gas and that's also my guess.
