Tesla was fooling around with that.

If they didn't stick with it, nobody will. Also, standardizing batteries across companies is just silly. Electric cars basically are batteries. If you standardize the most important element of the car, you will kill innovation.

Superchargers on long trips (~1600 km per hour charging with v3) are sufficient. It's 15 min of charing per 400km or 4 hours or driving. Charging at home/work everyday is actually more convenient than tracking discharge and going to some special place every couple of days. Building chargers at parking places is not expensive. From what I gather it should not be more than a few thousands. In bulk it's probably even cheaper.
