ELI5: Why are motorcycles so loud compared to cars?
gpt
1, Not all of them are.

2, Some motorcyclists prefer a loud sound because

2a, they think it's cool

2b, the vibration feels powerful

2c, they believe that "loud pipes save lives"

(that is, that when other motorists *hear* a loud motorcycle, they're not likely to accidentally hit it)

3, different muffling systems.
