If enough people think like you the carbon tax is going to be an everything tax (sea walls, relocations of populations, etc.) which is going to cost a lot more than a Tesla price differential.
Well... no, a carbon tax can/should be sufficiently high to cover those externalities. I'd support that. I'd probably wouldn't be able to afford a car at all anymore, which would be much more environmentally friendly than an electric car.

If you have purchased a Tesla before that point, others will be paying you for rides in your self-driving car as part of a ride-hailing fleet. Just a thought, might not pan out, as with any investment.
It's not so much about what you support... the tax will come down from above with or without your support. It's more about what investments are you willing to make personally, because that part is really up to you. There are risks, to be sure, but in the meantime it's a fun, safe car that doesn't cost as much as people think.
I'm willing (and have already) stopped eating meat, among other things. I can't afford an electric car. I'd be more willing and able to invest in a lifestyle that doesn't involve owning a car.
