I've seen that, too. But, like, how dumb do you have to be to think that? Or rather, how little thought must you have put into the concept? 1M miles at crazy-good efficiency, let's say 200 Wh/mi. That's a 200 MWh battery. We're currently putting 75 kWh - 100 kWh batteries into vehicles. So these people are (not thinking at all, or ) thinking that Tesla is sitting on a 2000x energy density breakthrough at somewhere approximating the same cost. And that if Tesla has this energy breakthrough, it would make financial and product design sense for Tesla to simply put 2000x the energy capacity into the vehicle rather than, say, 10x the capacity and a bunch of cost savings or some such.
