Person in a car listening to very loud music, pulls out without looking, car in the right hand lane crashes into the back of them.
Airbags deploy, crumple zones crumple etc, driver is fine.
So, little to no "danger".
Person on bike happily shooting along with headphones on, say they are listening to music at the same volume as a car driver, pull out without looking and get hit- that's them seriously injured.
Depends on how you define danger, does it not?
