I don't want fossil fuel subsidies either! We should focus on killing externalities like you said, especially environmental ones, and stop the abuse of our tax money. If Tesla is to succeed, it must succeed without federal subsidies. The subsidies at best hasten the advent of EV by a few years, and that is not worth the Billions of graft and waste that occurs with these federal grants, loan guarantees and rebates. Especially if it turns out the EV wont happen for another few decades. In that case, all these subsidies are a waste because the underlying battery technology is insufficient.

I don't know if Tesla will succeed or fail. If you think it will succeed, then buy their stock. But i don't want to be forced into investing through my tax dollars. That is not the role of government.
