One part of the answer is enforcement. Ticket the shit out of dangerous behavior and people will do it less. I literally never see anyone pulled over for traffic violations anymore, whereas it was common 10-20 years ago. What happened to traffic cops, and why don’t we have cameras that detect this shit? In Colorado people don’t even bother to renew their tags and there are no repercussions. It’s like fucking Mad Max out there, I hate it so much. Obviously making the world less car reliant is critical, but the lack of any visible enforcement is absurd too.
That’s entirely the wrong denominator for this comparison. IRS doesn’t write the budget nor do they write tax law, they just collect.
