Drag racing ice cream man

What the heck is up with the ice cream vendors on my block? As soon I hear the alluring ice cream bell I grab my wallet and run outside. Takes me no more than about 10 seconds at worst. I run out the door and he's either halfway down the block or tuned the corner. A man pushing an ice box shouldn't be able to move that fast! He's nothing more than an ice cream tease I tell you!
