Going back to "Master Plan Part 3" last year, the charging team had the worst presentation.
Home charging by induction, which is a dumb idea, just plug the car in. Unlike my phone or toothbrush, my Tesla takes a lot of energy, I would rather not lose 10-30% energy by wireless transfer.
That and I think the main reason is Tesla took millions in govt credits and funding for providing DC fast charging, but they were not actually meeting the requirements. (Tesla took millions in tax credits, but didn't meet the requirements that were set forth. )
1) "DCFC charging ports must support output voltages between 250 volts DC and 920 volts DC" (Tesla superchargers do not do this)
Other Tesla fans are stating other reasons. . . But I think it is a combination of bad ideas, illegal accounting, and corporate bloat.
