That’s not how this stuff works. I never sit in my car waiting for it to charge. Sometimes I’ll charge while shopping. Plug in the car, do your weekly grocery shopping come back, drive off. When you use a level 2 (shower) charger, you leave the car and come back after a couple of hours. It obviously depends on the available infrastructure in the places you normally go to. Takes a bit of planning and a bit of forethought. But it’s really not rocket science.
