a speeding ticket. In my mind that means I match the speed of the faster traffic (but not the fastest traffic). That typically puts me at 5-8 mph over the speed limit.
I'm curious if some these people are complaining about me. I proactively clear the passing lane if I see someone approaching from the rear. I never do so in the carpool lane. If they're not happy with my ~5 over the speed limit then I figure it's their job to carve a path through traffic
