The solution to EV range anxiety

I recently rented a Tesla. The car was awesome, wonderful amenities, neck snapping aceleration but at the end of the day it had to be charged. That part was not so much fun. There were cars lined up to charge, one sat plugged in. No owner in sight, one charger was not working. This is very much a problem for government policy to solve.

I suggest mandating standard battery packs. It's the perfect solution. You drive to a station, take a depleted pack out, insert a new pack, and you are on your way! 

If we're going to make the shift to green energy, then the infrastructure must be adequate to support it.
