How good are American roads?

as a brit I've driven through most of the US states and major cities, and they were generally comparable to what I was used to at home and throughout continental europe

Los Angeles though was something else, giant gouges on 12 lane highways every few feet for miles on end

and on sliproads, sudden surprise vertical walls with right angled bends

was like something out of the third world

Do you remember which highway you were driving? Interestingly this goes against my experience. I’ve actually remarked to many friends that I enjoy night-time driving in Los Angeles since the highways are well-lit and smooth (and of course, no traffic at night).
