Around San Diego, we rarely use any freeways but the I-5, and SR-56.

From what I’ve seen on those particular freeways, tailgaters, speeders, and my personal favorites–those who don’t know how to make a turn and finish it in the same lane–especially when entering or exiting a freeway ramp–seem to come in all varieties, so I can’t say I’ve noticed any particular group of offenders.

I’d like to see some stats on aggressive drivers and their net worth. Now, THAT would be interesting.

It definitely seems to be equal-opportunity idiocy on the roads, and other drivers, like the OP, have to suffer the consequences. BTW–Sorry to hear of your incident NP.
