Once the number of EV's get high enough, we can have recycling stations for them. Another benefit of having an Electric car is that you don't care about the source that produces the electricity. So tomorrow when cold fusion is feasible, we just build a bunch of them and power all our vehicles with the electricity that they produce.
However, I am interested in hydrogen as a fuel from a long term perspective. In the future when we have vehicles that need to run on other planets, presumably hydrogen will be the fuel; however I'm not sure those engines will be IC; maybe miniaturized jet engines? :)
edit: probably not, since jet engines need oxygen which may not be available on other planets
