I do not understand why it is legal for motorcycles to be so goddamned loud.
I was out for a ride around town on my cycle this afternoon. While I was waiting to turn out from a quiet residential side street onto a more major thoroughfare, a guy rolled up next to me on a motorcycle. When there was a break in traffic, we both pulled out. Motorcycle Guy opened his throttle and it was just ear-splittingly loud—enough that my watch gave a loud environment notification for 90 decibels. I could still hear him long after he was out of sight.
