I agree with everything you said in this comment, except for the lack of support. It's kind of a meme in online urbanist circles at this point that in the US you can pick either walkable or affordable. There's incredible demand for walkable places where you don't have to use a car, to the point where these places are not affordable for most people (I'm not saying all the demand for these dense places comes from walkability, but there is good research saying it's a strong factor). Your comment is also sort of based on the view that "whatever the (federal) government is doing is what the public ultimately demanded", which is clearly not true. Federal government agencies like USDOT act with a certain degree of autonomy, and their actions are very much open to public criticism as we are doing in this thread.

To bring up one more thing related to your point on rural and suburban areas, the low-density car-dependent development across the vast majority of the US is a deeply ingrained problem here. That is changing with more dense transit-oriented development happening across the country, but it will probably take decades for the needle to move significantly. And unfortunately the street safety measures that this money is going to are not going to help very much with this, which is sort of the point of the original comment.

These issues are all intertwined, but I don't understand the arguments in these comments that point out the problems are intertwined and stop there, as if that's a death knell for change (for example, political support for transit service is tied to the quality of that service). Yes, no one is denying they are intertwined, that is even why urbanists have started using terms like "car culture" that encapsulate the messy ball of issues. The more we discuss these issues, even online; the more consciousness arises in the public about how things can change, and things eventually do change. Hence the use of attention-grabbing call to action phrases like "cars are the problem" that started this thread, which provide an alternate framing.

I agree that the government isn't always following popular opinion. However, there is also a difference between idealistic opinion and reasonable opinion. People want better transit, but fewer people with to raise taxes for it, and fewer still can pock a tax they want to raise.

If it's such low density, is it really a problem?
