It's a mixture of different problems. L2 charging is pretty simple -- connect to existing AC grid, let people charge slowly. Needs to be everywhere (light poles) and needs to be robust and inexpensive. L3 charging is hideously complex -- you're dumping 5-10 single families of power into a cord, outside in the driving rain. You're getting billed as a commercial utility consumer where you're charged at your 95th percentile current draw for any given month, and you're paying commercial power rates. People will get mad if you vaporize their husband or hurt their car. But -- Tesla seems to have done L2 and L3 at scale. Other companies such as electrify america seem to be examples of malicious compliance or, at best, absolute incompetence.
