Tesla has done a good job making popular, well-rated cars. But this idea that they were "first" while others were "sitting on their asses" is just completely factually incorrect. Competing car manufacturers dipped their toes into EVs years before Tesla even existed, and everyone rushed to build mainstream EVs in the same 2007-2012 time frame, with Nissan and GM releasing their products first.[1]
[1] Also, I don't see the relevance of the Ford loan? I'm not the one trying to add a moral dimension to the history of EVs. There is none. The relevance of the federal subsidies is not "oh, Tesla took subsidies." But rather that subsidies were necessary to make EVs attractive to consumers. The EV1 was canceled because consumer surveys in the late 1990s showed that you'd have to sell an EV for $28,000 less than a gas car to get consumers to buy it. Rising gas prices closed up a lot of that gap, along with advances in battery technology improving range. But the $10,000 or so in federal and state tax credits also played a huge role in making EVs palatable to consumers.
Finally we can even take things like the federal automotive bailouts. Ford, for instance, took a sub-inflation rate loan of $5.9 billion from the taxpayer, which they unsurprisingly have not paid back. It was supposed to be used to develop fuel efficient vehicles. A literal check for $5.9 billion just blows every point in your list out of the water. Yet, Ford not only dawdled but most recently announced they've cancelled every sedan/car in their line except the Mustang and one upcoming vehicle. That leaves them 90% of their lineup distributed towards trucks, SUVs, and commercial vehicles. And the next time gas prices spike, we can bet they'll come begging for another handout from the taxpayer. Just brilliant business acumen by these guys.
