Cars sound great. Crossing the double white lines is a no no though. Can appreciate its probably the middle of the night or early morning but just reminds me of the amount of people who cut across lanes in the Clyde tunnel every morning.
I drive a f150 with twin exit ss exhaust and every tunnel you can't help give it a we burst, even love going through the city and listening to the v8 rumble bouncing of all the buildings
I live in the tenement right next to the south exit of the tunnel. Sometimes at night you hear something with a brutally loud exhaust racing through. It pisses Mrs Monkey off but makes me smile!
