Few years back, I was on a Honda Dream (look it up 110cc) doing 60 km/hr, some idiot motorcyle taxi (yes, the kamakazi's of Bangkok) passed between me an an construction fence, clipping the handle bars so I went right over the front and the bike went left.
I was propelled like a 6'4" log :squid: rolling down a busy street with buses that stop for nothing, I repeat nothing, not red lights, not pedestrians and certainly not for human logs.
I have to say, the rolling seemed to last forever! Monentarily I attempted to slow the roll by spreading my arms and legs... bad idea, the impacts we sever (yes only 35 mph). So... I kept nicely compact and just rolled along praying for no traffic.
Lessoned learned. Don't fight it... roll with it. Praying helps... mine were answered! When in a heavy traffic situation try to get out of the way of on commng traffic. As others say... don't rush, but don't lie there waiting for the next bus to run you over. Crawl, even if you think you can walk, this is no time for bavado, I never seen anyone get medals for jumping up after they just slid 100 meters over asphalt. Crawling keeps your head low and your blood pressure more even. You are less likely to stand up and faint. Again I am not saying you should move at all it you can safely lie and count to 5, 10 whatever. But if you're in grave danger, crawling is better than walking.
Be safe. I took this tumble in short sleeves. Nothing boken, but I left a lot of skin behind. Now I ride with a padded jacket and at 40C it can be hot, but I found an airated one so once I'm moving I cool down. So no excuses for those of you in moderate temperates.... suit up! Live to ride another day!
