Agreed, i can’t believe you can get ticketed for a broken taillight but someone can ride a Harley and disrupt hundreds of people anyone, basically anyone within a 50 meter radius, in total impunity.
Honestly it could almost be considered assault. I’d rather be slapped in the face walking down the street than being woken up by a Harley owner at 02:00.
In the US you have so many Harley's too. At some point (as a kid) I was really impressed when a Harley came past. "WOWWW! Imagine what it would like to be that guy!". Eventually everyone got a Harley and every single one of the riders needed a super loud exhaust. It's certainly less impressive today.
Maybe because lots of cops like Harley's with straight pipes, or are sympathetic? But they'll certainly ticket bassy low-riders.
