*YES, I HAD A HELMET ON* Stacked my Vespa on Nov 27 2007. Hit a stopped car at around 80kmh (50mph), facebutted the dash, flipped and went through the rear windscreen face first. She'd stopped in a lane with a no-stopping restriction while I was behind her changing lanes with my head turned. It was hot that day so I left my full-faced helmet at home and wore the open face helmet with jeans and a shirt. Oops! Only spent two days in hospital after the doctors told me I would be there for up to 6 months. Was due to fly to the US on the 29th but put it back until Dec 17 which with hindsight was a little too early to go. Finished up with 4 full-thickness tears to the face with my bottom lip almost torn completely off, very deep puncture wound on my hand from brake lever, two very black eyes (lucky I had my sunnies on), glass and gravel all through my face which had to be picked and then sandpapered out, bleeding on the frontal and left temporal lobes of the brain, severe cuts and abrasions to both legs, teeth were forced back into head and very crudely wired back into the wrong spots (the guy who cut out the wire said it's the most brutal thing he's ever seen), a large hole above the right collarbone from the mirror stem, severe shoulder + elbow damage to both sides and a fair headache.
Much better now, I can almost feel my face (less info)
