After playing the first few levels of The Simpson's Hit and Run, my vivid imagination has lead me to the conclusion that the design mission statement was "GTA3 Meets Rugrats - all the driving mayhem, without the guns, in the child friendly world of Springfield".
It's a fun game, tons of character audio clips, great for fans. However the most annoying parts are the video tearing (which most people wouldn't notice unless you've worked with a lot of games or are familiar with video coding) & the craptastic camera control that tends to get "stuck" behind things.
Overall, it's a great "pick up" single player game - well worth the $20USD
