The main low-hanging fruit is just removing surface parking lots in American downtowns and stopping the development and expansion of highways through the same. If you did nothing else that would have a significant positive impact. For almost all communities those surface parking lots are economic extracts from the community. They're woefully underpriced for tax purposes too.

Maybe the parking lots, but if you know anything about the major Japanese cities with satisfyingly good train systems then you'll also know they have a lot of expressways running through them.

		Yes, I do love the rail system in Japan. Went a few years ago, going back next year most likely. I've also driven in Japan (Osaka). I just meant, in general, a low-hanging fruit we could tackle is making surface parking lots a thing of the past in downtown or urban areas. With actual economically productive constructs there instead, such as business, retail, housing, parks, &c. we could pretty much get to the density where trams make sense, and in some cities we could work on intra-city rail too. I think where I live (Columbus) is very well positioned for this model if only our civic leaders had courage and stopped thinking of transit as a "blue" thing (also our city council needs to stop suburban thinking). We don't need to build any more expressways or highways. We are maxed out. The only sane option is respecting appropriate density, and focusing on categorical changes in how we move people: walk/bike/rail instead of bus/car/roadways.
