"It makes a bit more sense if you think about Tesla's valuation as a bet on future potential." In my opinion that's a very small bit that can't possible justify the current price. If I was going to justify investing Tesla today I would have to make the case to myself that my ROI on Tesla would be better then my other possible ROI I could get else where. Let's say I am hoping for a very reasonable 6.5% return, based on rule of 72 I would expect the value to double in ~ 11 years. Assuming Ford grows at a similar rate over the next eleven years Tesla would have 4x the market cap as Ford currently does. I just don't see how you could expect to invest at the current levels and expect a reasonable return. Even if Tesla perfectly executes for the next 11 years there is no way it would be worth it's current evaluation let alone have room for a decent ROI.
