because of Tesla/Model S purchases (vs the prior high-end sedan purchases which were largely from overseas manufacturers) Tesla/Model S "miles" (fueled by 100% domestic fuel vs say 50% domestic petroleum) ??? i.e., Savings from difficult-to-quantify environmental, health and other benefits aside, the financial benefits from the above fact(or)s alone might justify not only the federal and state incentives, but possibly some of the sales of ZEV credits that nay-sayers and haters love to cite. Someone else might be able to provide a finer analysis (or discredit this notion completely!), but here's my very rough and 'round numbers' analysis: Let's say 40k units at $75k each = $3bn; very generously, $1bn would have gone to the Big 3 in Detroit (stayed in country) anyhow, meaning $2,000,000,000 stayed in the states. Federal tax incentives on those vehicles? = 40k x $7.5k = $300mm, for a roughly 7:1 "return" or benefit to the U.S. economy. Say 600 million (? is there a counter somewhere? ) miles, = 20,000,000 gallons @ $3.00 / gallon, half of which would have left the country... resulting in $30,000,000 that has stayed in the US economy from petroleum "non-expenditures" alone. So where does that leave us? Well over $600 million per year is staying in the US because of the Model S. And even if most of it weren't going toward well-paying jobs in the all-important "STEM sector", I think that would be a good thing. No? I haven't seen this point spelled out anywhere before, so thought I'd try it here.
