By my read the money went to state transportation departments, or at least 5 of the $7B.
It sounds like a lot of money, but look at these high speed rail cost estimates. I do visual segments are HUNDREDS of billions of dollars. To re-design city bocks in Metro areas across the country is also quite expensive and ONLY benefits the people of those cities.
If we are going to make a swap to electric cars, which is IMO more plausible than a complete eisenhower-esque infrastructure overhaul, a fast and reliable charging network is a necessity.
Hate Biden if you want for in rental progress, but at least there IS some progress. I can't imagine it's easy to move the needle when an entire branch of government (the two houses) will actively vote against their own plans to keep Biden from getting any wins at all.
