No no, I've said ten times the best thing you do when you buy a tesla is contribute to furthering the technology. The issue is with thinking that good things are actually happening when you buy one. A tesla may be relatively better, as in, it's relatively better to only rape twelve women instead of fifteen, but it's still deep into the bad category.
Lots of bad environmental things are still happening when you buy a tesla, but there's this drunken fanboi element that keeps people from seeing it. They're cool cars and I'd love to have one, but they're still environmental disasters, just maybe a little bit less of an environmental disaster, though we don't really know, because who knows what happens when there are 20 million a year being recycled.
My only fight here is against the ridiculous overhyping them into being some rolling garden of eden, when really they're rolling cancer clusters just like the rest of them. Beginner hippie level 1 people(i.e. electricity will save us!!) love them, but someday people need to make it to level 2(i.e. oh shit, the problem is actually consumption of any medium, because everything is either very toxic or very finite).
