It’s LA...Everyone drives way too fast for conditions and their skill level...One residential area I lived in, vehicles routinely traveled at 50++ miles per hour in a RESIDENTIAL neighborhood.
You’d slow down to pull in your driveway and these lunatics would be honking their horns because people dared to slow down to pull in their driveways. It was a mad house.
We have the same in our neighborhood in Reno. Not just kids either. 25 zone and 50 and up are not uncommon. Drag racing up hill three across? Yup! Being passed and nearly to boned turning in driveway is not unheard of. Cops? Once in a while they venture out.
