Insanely close call for me. I t-boned a VW going 30 miles an hour. I slammed my brakes and braced for impact.
Flipped over the hood, legs hit the bars, landed on my head on the other side without a helmet.
After a few seconds of "WTF just happened," I got up, looked at my totaled bike, felt my bruised legs that I could barely walk on...
Since that day, helmet always, never bomb stop signs. I got a sweet colnago master x light out of the accident though
