We absolutely should be ending subsidies on fossil fuels, the meat industry, and other polluters. This will cause a ripple effect on the cost of everyday items and the standard of living globally, so of course there will be those that say it can't be done. The problem is the game of musical chairs will eventually end, either when we're completely fucked or at a time of our choosing.
Ask they have to do is scale back 1% the first year, 2% the next, etc. The second it looks like a long term investment won't pay off they'll stop making them. Then we'll see supply chain issues slowly increase which will force fleet vehicle purchases over to electric or hydrogen faster.

Demand will reduce for IC vehicles and so on.
