I can't see that happening. Yeah, there is enough Tesla frenzy that they are selling everything they can make, but I'm pretty sure the other 99% of car owners see them as transportation and will wait for EVs to get some track record at the standard price range before they jump on the bandwagon. You can buy a 150 hp lower end car for $20,000. When you can get a comparable EV with 200 mile range for that price then we can start to talk about EVs making inroads. Until then EVs will be ramping up, but it will still not be the main driver in the auto market.
Also, in 5 years Tesla will not be the major player in the EV market. They will be swamped with competition and had better figure out how to make them cheap enough to sell for well less than $35,000 and still make profit. That's what everyone else will be doing.
