I lack the commenting impulse control to say this in a politically correct way so my apologies for the outrage that will follow, but to put it crudely there is someone in my extended family who became a retard after falling off their bicycle at roughly walking speed and with a helmet on. It's rare but you can easily die just from walking and slipping on a banana peel.

While you're right about slower generally being safer, you should still treat it like a life-altering tragedy could happen at any time and like you're going 200 kph.
