I don't think the US is ready for a compressed gas powered car. Natural gas vehicles are basically gone except for some fleets, and there was already extensive distribution of natural gas. The fuel tanks on compressed gas cars expire, and chances are it won't be economical to replace them; it certainly wasn't economical to replace natural gas tanks when I was looking circa 2016. When cars are lasting longer and longer, having a 15 or 20 year ceiling on the life of a vehicle that's not connected to the amount of use is a problem. EV batteries might wear out over time, but that's more connected to number of charge cycles than how much time has passed.

Maybe it took too long, but we've got a single standard for high powered charging going forward, and I think J1772 is universal for PHEVs and slow charging of EVs. Eventually, people running charging networks will figure out how to keep their machines working and add card readers. My favorite broken charger is the wireless ones --- someone has run off with the cable, but hey the advertising display still works.
