I do it everyday on the way to work. If I don't I just sit in traffic and idle. When it's time to move forward, just walk it, not even into gear.
The most dangerous part is the people that try to block the way. I give them space then when they move over to block, I pass on the other side. Oh, and I scream choice words through my helmet. I don't think they hear me tho. The air horn also works really well when I get next to the worst offenders.
You know who you are lady in that volvo on your cellphone with your chihuahua!!!!!
(yeah, I've met her a few times on the commute)
Most important in Kalifornica is not to split much faster than the cars are going. I got pulled over once about 9 years ago. I was doing 60, speed limit was 65 and I figured nothing wrong. The cop kinda pointed out that traffic was doing 20. Ok, ok, never did that again. Lesson learned. I don't go more than 5 - 10 over traffic. If they're stopped, I'm barely moving just enough to keep it upright and able to stop on a dime. Never know if the wreck is just around the corner ahead.
