// This results in multiple things:
// - When on your own, you will hear your own engine sound extremely clearly.
// - When you were alone but someone is gaining on you, yours will go quiet, and you can hear theirs more clearly.
// - When around tons of people, engine sounds will try to rebalance to not be as obnoxious.
