(1) Drastic increases in gas and car taxes would be highly regressive, and disproportionately affect the poor.

(2) Housing prices are rising in large part due to foreign investment / money sheltering. I doubt that you could plausibly increase gas and car taxes high enough offset this, and it would be outright dystopian if you did.

It really seems like we should be able to directly tax the foreign investment in order to improve public transit... I don't have any good ideas on this however.
