I drive in Taiwan, and I drive in LA. I find driving in LA freeway is terrifying.
This weekend, I drove back from Las Vegas to LA thru Interstate 15. The average speed for all cars is about 75 miles an hour the whole time (that is 120 km?), facing the sun, while many young people with fancy cars weaving in an out. Many would cut in front of you, if you leave a space just enough for them to cut in. They could then suddenly break in front of you so not to hit the car in front.
When it is close back to LA basin, the long steep down run is even more terrifying with no room for any error.
I do not know how you prepare people driving in LA. Comparing to LA, driving in Taiwan is much slower.
