OK, so in 2010 I drove from Vegas to LA as a passenger. This time, I'm doing the driving (I have a full UK license and an international drivers permit). What's it like for speeding on the 15? Last time I went the flow of traffic was 85-90 and we just kept up with that. I'm going to be driving a white BMW with heavily tinted windows, large rims (stock BMW ones) and no front plate. Should I be more cautious? I could do without spending a few hundred bucks on tickets. Also, what's it like in LA for doing u-turns etc. Are the cops there particularly "vigilent"? As tourists we may get a bit lost going to Malibu, Santa Monica etc.
