One of my favorite motorcycle campaigns from the last decade or two has been the GearUpProject. I've been sporting one of their stickers on the gashed up side-panel of my V-Strom since I gashed it up (2007 or thereabouts). This group accumulates statistics on riders, crashes, and the effectiveness of gear.
I stumbled on this sneaker/flip-flop wearer's pre-surgery/post-clean-up shot and it is a gross reminder of the high cost of hoping for the best and planning for the same. Nature loves vacuums and hates fools. Like my experience with scooter-ownership, if you aren't smart enough to imagine how much damage sliding down the road at 5-75mph will do to your skin, you aren't smart enough to ride a motorcycle (you can own one, just don't take it out of your living room). The old "Death on the Highway" films the Highway Patrol used to show to high school kids to gross them out and make them consider sticking with bicycles for a few more years before venturing on to highways in Mom's Buick, this kind of illustration is a good reminder of how poorly we are constructed.
