That was pretty funny. The animation and Sonic's voice at the end were kinda weird, but I like the overall content. You did forget the most obvious reason for a car though - the drive-through.
Sonic for life! Avenge him goddammit, avenge! But still, Sonics just being lazy if he needs a car because overall he is SONIC! Also, the car in this flash looks uber-slow.
Reaons #3 and #5 are good enough for me (lol). Good flash there.
forgot reason #6 being cuz "he wants to make the race fair and fun for everybody" but hilarious vid!
it was kinda dumb :/ no point and it wasnt funny
