I agree completely. I lived in Los Angeles for five years in the 90s and a motorcycle was my only transportation. Being from Texas, lane splitting was new to me and my first time giving it a try was not great (I had taken my helmet off and attached it to the side hook and as I went between cars I kept hearing an odd thud. When I finally "felt" the thud I realized I was smacking car fenders as I rode by) It was an embarrassing learning experience. But once I got the hang of it, it was wonderful.I wish lane splitting was legal here in Texas. Most of the time, there's no issue, as traffic is sparse enough. But in the metro areas, it can get really backed up. Sitting in your car, with air conditioning, and stereo entertainment is one thing. Sitting on a motorcycle, having to balance the weight with your feet, in the heat, and breathing all the exhaust fumes is something else. Car drivers who complain about motorcycle filtering ought to be made to experience about 20 minutes of bumper to bumper traffic while riding a bike. I think most of them would soften their opinion about it.
Motorcycles have a greater power-to-weight ratio than most cars and usually leave them behind from a standing start. So letting them go to the head of the line at stop lights not only made more room in backed-up traffic, but let the motorcycles get out of the way much faster.
