Today I rode from my home just north of San Diego to the suspension shop I use on the north side of LA, it's 100 miles each way. I went there to get my forks revalved again, I wanted them a bit softer.
If you haven't ridden on LA freeways the speeds will probably surprise you. I held it at 5,000 rpm the whole way, both ways. I wasn't passing anyone.
Standard speed is 90+ mph on Southern California freeways, never mind the posted speed limit of 65. Try to go less than 80 in the slow lane and you will probably get run over.
