On the density aspect, I was just reading: https://www.accessmagazine.org/fall-2010/density-doesnt-tell-us-sprawl/ https://www.accessmagazine.org/fall-2010/density-doesnt-tell.... I'd agree that having "evenly" spread low-medium density rather than "lumpy" density is part of the issue, but from what I remember observing in the parts of LA I've spent time in (mostly around Venice) is that the density seemed to definitely be high enough to support getting around without needing to rely on cars (whether via powered scooters, bicycles, walking or public transit), but the sheer amount of space dedicated to roads vs footpaths etc. and the general layout of the streets and distances between retail centres etc. seemed to make it clear the cars were the expected way everyone would get around, and hence that's exactly what everyone did (maybe it's changed somewhat since I was last there ~15 years ago?). Certainly it was hard to understand the lack of rail-based transit options (whether heavy or light rail).
