I honestly thought that the GRID couldn’t handle it and with 40% of electrical power coming from coal, it made no sense...
I find a lot of exaggerations on both sides, pro and con. Sigh… For instance, Nevada is not losing billions to Tesla, as Tesla is being forgiven taxes that have yet to be generated; no Tesla means no income generated for the state. If Tesla is wildly successful generating much sales, others are calculating "lost" taxes on those sales. The ripple effect will generate maybe 30,000 jobs that will generate taxes.
Anyway, the GRID as you say it, is in poor shape. And electric cars are not green, as the electric power is generated by burning coal and natural gas elsewhere with a loss to transport the electricity. Sure, the GRID may be able to handle 35,000 new electric cars (although with brownouts), but seriously who thinks it can handle 500,000 new electric cars? Tesla was talking about building battery swap stations, where the battery could be swapped out in less than 15 minutes. So where are they? That turned out to be a promise they are not keeping.
