I have a performance exhaust on my bike. It comes with a decibel reducer which I keep on for daily use, and remove for road trips. Making noise in urban areas is a 100% dick move.
As a friend likes to say: " Look! there goes a son of a bitch riding a noise"
Actually, most planes from that era circulated air front to rear and smoking was always the rear section, and the entire cabin’s air was renovated every 1-3 minutes, so unless you were seated in the row immediately before smoking, you didn’t get smoke.
