Same with anything in life.
Same with a car, just less so. Of course you could also stay at home, wearing protective bumper suit 24/7 (and can still die from any number of things anyway).
At some point there's a tradeoff people make. Some people make it where the tradeoff slider says "motorcycle", rather than stop at "car". And I'm not talking a tiny niche, but about 1-1.2 billion people globally.
