Wow five whole hundred?
If you really think about it, all the EV subsidies need to go the charging infrastructure. Tesla has already proven people want EVs. The real challenge is the charging for people without houses. Right now much of DC Fast charging falls on Electrify America's hands and they really do not care at all as they are just a punishment company for VWs diesel cheating scandal. In my and a lot of other experiences, up to 25% of public chargers are broken and can take months to repair. Only Tesla has decent organization to fix it in just a couple of days. People who buy EVs now are in for a rude awakening.
