I think drivers know we're listening.
I mean, every day they've got something to say:
Get the **** off my road!
LOOK OUT!
Why is HE in traffic!
Ah ****, not him again!
I also would miss out on the guys/gals who:
Squeal their tires to show me how much speed they've built up at the stop light
When they throttle their engine hard, to show me how Pepboy's Automotive helped them achieve better RPMs
Seriously, why would you want to listen to anything less than the hateful symphony associated with the general public and driving??!?!?!?!?!
And who can forget the guy who's pushing 2k watts of subs for YOUR pleasure. I mean, he spent all that money so you could hear what he's listening to, obvsly.
