> The biggest problem is that while slow charging (L2) in your own garage would be perfect for 99%+ of people in the US, and isn't even very expensive, that's a barrier to entry most people do not want to screw with.

I feel like this is only an opinion that people who have never actually used an EV have. Plugging in my car overnight at home every few days is infinitely more convenient than needing to drive somewhere to plug it in somewhere else. The actual charge time is irrelevant as long as it's not more than ~12 hrs.

I leval 1 charge my car and that is always enough. Salesmen who sold it to me says he does the same. It depends on your commute, (i typically ride my bike if the weather isn't too bad) and the other trips you make (why I bought it - there is a once a week trip I make outside of bike range)
