Sorry, I didn't see any other connection from when you said this:

My point is just, what infrastructure can you do with say <$1b? It’s a lot of money but not building a whole new railroad kind of money. You can get a few station upgrade projects, a couple of electric trains, etc.

There’s room for private funding of a new electric car company. Save the tax dollars for big infrastructure projects.

My bad, but I don't see the relevance otherwise - the tax dollars are already being saved & spent on big infrastructure projects, and the privately funded car company is also underway. Both are already facts.

Nobody is getting rid of cars or making any transitions overnight. How did you come to this anyway?
