The increased rate of innovation (measured in months rather years) that is customary in SV has the perverse effect of hurting resale value. Think of how quickly an iPhone depreciates. This is good for bargain hunters but increases the cost of ownership for original owners.
You can get a much better car for the price of a Model S. The price premium pays for prestige/coolnesss over stodgy old BMW/Porsche/Lexus, which is dampened signifantly in the used market.
Can you name one? For ~$55k, it's tempting to go gas-free even on my 75mi roundtrip commute as opposed to my 50mpg (10yo) Prius. Other options are non-viable at that range.
Model S starts at $69k. That's a lot of car. The model Consumer Reports gave 100/100 to is the P85D, at $105k. That's a ridiculous amount of car.
If you're looking at sedans/coupes: BMW M235i or 328d xDrive ($50k), BMW 5-series ($60k) Mercedes E250 diesel ($63k), Audi A6 ($56k), Porsche Boxster ($59k).
I wouldn't be sad about my money going to fund cool battery technology and saving the environment. But you could also use it to buy more car.
The price premium for Tesla over a similar gas or diesel luxury vehicle is conservatively $20k (since the BMW M and 5-series are closer to the P85D than the base Model S). Figure diesel is at $2.50. The 328d and E250 both get close to 40mpg highway. You'd have to drive more than 300,000 miles to break even on the electric, and that's before you consider the price of electricity.
