I don't know, daily commute, if a car is slowing ME down, I'm going to pass the slow moving vehicle.

pass the cars, pass the cars, pass the cars.

if there's a lineup, I'm splitting the lanes. Cars split lanes with bikes all the time, I'll split lanes with cars when I consider it safe. I even split lanes on drawbridges with backed up traffic.

I filter at traffic signals, pull right up front, then put the hammer down and continue on my merry way. I'm often ahead of the cars at the next light as well, depending on road conditions, grade, etc.

I really don't care to be stuck behind slow moving vehicles like cars when I can get well ahead of them off the lights.

Ever heard of the terms "traffic pacing" and "traffic signal sprints?" These are weighted terms describing true vehicular parity in dense urban traffic. splitting lanes, filtering, are techniques employed in traffic pacing to stay ahead of blocks of cars moving off lights thru dense urban cores.

You can stay behind all the cars, for me, NO THANKS, I'll split a lane, pass a car, and claim the lanes with the best of them.

If I'm slowing a car down, and they pass me by splitting the lane, well, WE ALL KNOW cars do that ALL THE TIME.

but you're right, sometimes a bike will slow down a car, and sometimes a car will slow down a bike.

But if I can bunny hop the curb, ride on the grass in suburbia, and pass some clusterfuzzle of cars stationary on the road, I'll do so. Curb hopping to get around clusters of busses blocking city streets (happens sometimes in downtown Seatown) is an OK technique for me when I am confident I can perform the pass safely.

pass the cars, pass the cars, pass the cars.....
