I think a fuel tax is superior while electric vehicles are still in the minority. Not only are the privacy implications much less severe, but bigger, more damaging and more polluting vehicles pay more per mile. Congestion charging should be zone based rather than road based, because of the perverse incentives that would create for rat runs on otherwise quiet streets. And doing it using concentric zones again decreases the privacy damage.
