I like the idea of adding conduit to the parking spaces of residential units to accommodate future EV.
not sure i like going to a 20A combination AFCI / GFCI protected car plug though as this will likely trip with older block heaters. no doubt homeowners will get annoyed and simple change it to a not GFCI receptacle.
going to 250kcmil for 200A services is overkill, 4/0 has been used for decades. also if we have to go up in cable size, maybe manufactures should increase space and install larger lugs in their equipment.
