Loud fucking motorbikes

why the fuck motorbikes have to be so fucking loud with their 200 quid exhaust just so they can get 4mph faster and 0.02 second quicker?? it´s all fine and dandy to the motorcycles but fucking annoying when they drive right outside your flat shaking the old windows and so loud as if it in the same room as I am.

Same reason some go for the Arrospok. Because it's possible.

and why the fuck do they have to accelerate like a bat out of hell after the light turn green when the speed limited is only 30mph??

Can't help you on that. As long as they don't do it
a) starting from the advanced stop area for cyclists and
b) passing within 6 inches of me
I'm not too bothered. Yeah, they look like twats to the non-motorcyclists, but we look like twats to them. 6 of 1. Half dozen of t'other.
