Possible future customer, but it looks to me as if it's only really his wrist and collarbone that are at any big risk. Low speeds and manageable heights make the risk fairly low, I reckon. Not like the time I had to call the Kingussie ambulance, when I was cycling happily along a Sustrans path and my dad missed a corner. The combination of a strong tailwind, a gentle downhill and a sharp bend in the cyclepath with an unguarded drop hidden behind the greenery made it a veritable honeypot of potential ambulance customers.
