Simple but not bad at all!
I liked the voice acting, it was pretty good. The story itself was midly amusing, and the punchline that explained why he didn't care was pretty good.
Visually, though, while the graphics were okay, the guys looked like tiny little kids in the car (was it supposed to be a hummer or something? heh), and the lack of any background whatsoever, just whitespace, was the biggest problem with the flash.
Make a nice colorful background (preferably animated), and you'd have a greatly improved flash (and probably score). Still, good job overall.
