It's a bit like Amazon. Little prospect of significant earnings, but able to kick the can down the road indefinitely at current interest rates. And very hard for competitors (especially ICE car companies) to catch up. So being overpriced doesn't mean the shares are going down. I'd be on the lookout for takeovers/short squeezes. Self driving cars are a big deal, but they won't get approval until they prove big increases in safety. Tesla is the only maker already able to collect enough statistics.
