A $50/ton carbon tax would only result in $0.50 per gallon tax. I can't see us going so far as to make carbon cost $500/ton and that's what a $5/gal tax would equate to. So I don't foresee $8/gal anytime soon. I suspect we'll see a nation wide ban on new ICE vehicles starting around 2035-2040. By then I'll probably be driving an EV already. So maybe it doesn't matter.

If I continue to work from home after covid ends - and that's looking pretty likely at the moment as my primary client is moving to permanent WFH - then it won't matter. It's been more than a month since the last time I bought gas. I think my average weekly driving distance right now is about 5 miles to run to the store once or twice. If I drive 10 miles per week - I'd only need to buy gas once every 6 months. So in that case - maybe I can justify driving an LC200 instead.
