sudo bike 
It is rare for your average adult to crash solo and die. That probability seems to go up when intoxicated (shocker), but the chance of a sober adult dying on their bike without the "help" of a car are really slim. So slim you may as well don body armor and other equipment that has only an off-chance of doing anything to help you.

Clearly, people die in car accidents while wearing seatbelts. By your flawed logic, people shouldn't be using them!

This is deeply silly. Sudo's logic is that helmet's aren't worth more worth wearing than body armour because there is no measurably greater benefit for the helmet. NOT because the helmet doesn't have a 100% success rate! Seatbelts have a very high success rate; cycling helmets have an approximately zero % success rate in a serious crashes. Not the same. Not even nearly the same thing. In fact,
about exactly the opposite thing.
And really, if you can't be less silly and cognitively illiterate than this, please don't waste people's time posting.
