This is honestly why I tell people commuting to work to get moto gear. Having an impact rated helmet and pads, padded hard knuckles, and your countries self defense option of choice tucked in your jacket is the only real insurance policy for murderously negligent cagers. Bike helmets aren't suitable for road riding. Although I don't know if CE back armor would help a man who got hit hard enough to "[tear] his body apart". Although I suspect thats more describing the severe road rash that requires expensive moto gear to prevent.

Unseriously: I as a patriotic American keep a 200. caliber AT hand mortar on me for all my bike rides for self defense reasons.
