It is affordable, at least as much so as the equivilent size/performance BMW or Merc.
If you've got the high 6 figures to spend on a luxury performance vehicle a Tesla S costs about the same as a liquid hydrocarbon powered car. There might be the battery replacement down the road, but lower running costs until then pay for that.
Where EV vehicle economics fall down is at the level of the ordinary mass market car.
I’m not talking about Mercedes or BMW price .... I drive a Mazda 6. I want to see something other than an egg in a more affordable price range.
