>they only shifted the problem once again

Shifting the problem is a sometimes a good thing.

In this case, because it means the energy can now come from effective sources (nuclear) instead of carrying petrochemicals in the vehicle.

I live in a place where the largest sources of electricity are nuclear, wind, and hydro power, simply because they're cost effective for the region. So electric cars here shift not only to an easier problem, but to a largely solved problem.

As in math, transforming one problem into another is often just as good as finding a direct solution.
