First of all, nobody gives a shit about level 2 chargers, and we should just ignore level 1 completely since they are so slow. They're destination chargers and you should have at least one for every EV on the road. Touting these as viable public charging only causes confusion and distrust among the general public regarding EVs.
Level 3 is what everyone cares about, and that's what needs some level of parity with fuel pumps. Lack of level 3 charging is what leaves people with EVs stranded, and stranded EV owners is bad news for EV adoption.
Furthermore, it's not enough to have level 3 chargers installed. They have to be maintained, and that's the biggest issue with charging right now, broken chargers!
