I realized that we may soon live in a reality where that's not an option, but I bet the car he had still allowed him to turn off the radio with the ad.

(I'm sure there would have also been countless ways to make the thing play actual music, but turning it off is the most obvious course of action.)

ok ... but why would you listen to the ad - and nothing else, jsut the ad - for 45 minutes straight? it's not like there aren't a billion other options.
