Totally agree - which is why E racing holds zero appeal. Noise and smell. Tyre squeal is not that attractive.
I think Western Springs Speedway have a noise limit of 85db, yet we are on the North Shore and can hear the rumble/resonance!
I have a decibel meter app on my phone. Out of interest, I tried it at a dance competition in Melbourne - 87db. The band on a cruise ship, in the atrium, also 87db.
Donington last time I went, decibel limit 105db. I think Pukekohe was 95db.
