You can charge any of them off a standard socket, so no, just no faster rate charging at the house.
Having a dedicated circuit installed with materials for the wire, breaker fuse, and conduit was $600 including electrician labor.
There is a universal charging standard. The ONLY company that doesn’t follow it is Tesla, but they too can use the universal chargers which also have multiple plug heads to use at source or you can carry one in your vehicle.
As for the lack of charging stations, you obviously don’t own an EV. The sheer mass of stations makes it possible to drive from 29 palms to Manhattan without worry. The cars will auto-add and find them for you on your route, and tell you which you need to hit with what charge time. You can even filter on types and cheatgrass rates for them to calculate your trip. This of all the things you stated is a tribal non issue that only gets even less with time.
There is a huge problem with charging but electrical connections and smart circuit load balanced charging at various times on the grid is easily doable in the time ranges of adoption we are seeking. There is a current chicken and the egg problem where government doesn’t invest in massive infrastructure because private companies haven’t crossed the tipping point on making it their primary focus… who haven’t done so because their customers lack the charging infrastructure and so around around it goes.
Having governmental targets like California’s are ways to break that cycle and force investment that makes public infrastructure changes viable to due to economies of scale.
