It always surprises me how many steep hills are in LA.
There’s a very steep street in Signal Hill, Cal (oddly named Hill Street) that I remember driving as a lad. You go over and keep waiting to see the road, and keep waiting to see the road. I just YouTubed it and the main difference is that there are now buildings on either side. I remember it being just oil wells.
There was a case of something like this in England where the GPS sent traffic through villages that couldn’t handle it. Some streets were smaller than the semis trying to navigate them.
