Have you ever been passed in rush hour traffic on the freeway by a motorcycle splitting lanes? In S. California it happens all the time. Well this weekend as one shot past our car and pulled ahead you could hear a big bang and see a big cloud of dust just ahead. Traffic spread out as the bike popped out of the dust cloud without the rider. I stopped to block traffic and see what I could do. In my earlier years I was a paramedic and though maybe I could help. Well this rider was a young kid and his injuries were pretty severe. He was having problems choking on blood and I got the bad side of his chest down so his injured lung would not bleed into the good lung and end his breathing. He had no feeling below his waist and no pulse on his bad side wrist. He had no idea where he was or what he was doing and the pupil on his bad side was fixed and dilated. I kept him as alert as I could and kept working with him to keep him breathing and working with him so he would not aspirate more blood into his good side. The fire department and paramedics showed up and took over and off he went. And all this for what? A quicker trip down the freeway? He left my care with a lot of serious problems including a pulse well over 100, running out of blood volume and suffocating with a collapsed lung and circulation on his right side all but gone and a serious neurological problems. He may physically survive but this stunt will be with him the rest of his life. The person he hit has a totaled car and went with the second paramedic unit. When the bike passed me I was slowing down from about 75 coasting because there was traffic ahead. The bike was going at least 95 and the car he hit was going about 50mph, switching lanes. I saw the turn indicator, heard the bang and saw the cloud of dust. It happened pretty quickly. I think the bike rider, despite his speed and ability to split lanes was late to where ever he was going. I've always though lane splitting was dangerous, and now I now just how dangerous it can be.
