Don't kid yourself... Project 2025 section on transportation suggests removing nearly all federal funding to alternative transport modes in place of state by state funding, and the only thing that 95% of State DoTs know how to do is build and widen roads.

If funding must be federal, it would be more efficient for the U.S. Congress
to send transportation grants to each of the 50 states and allow each state
to purchase the transportation services that it thinks are best. Such an
approach would enable states to prioritize different types of transportation
according to the needs of their citizens. States that rely more on automotive
transportation, for example, could use their funding to meet those needs.
Implying cars will be affordable after tariffs. Cars from the past ten years are unreliable as hell. Everything before that is getting ran into the ground. Most people are priced out of the new car market.
If there's no alternative transport, people will be forced to buy cars at any price, preferably with a predatory loan. I don't think making cars more expensive is going to have the effect of making everyone cyclists if there's no investment in infrastructure to enable this.
