simple answer: no. real answer: assume that it does not, then, the friction of the wheels against the ground will not exist, leaving your car to spin its wheels quite happly without going anywhere. on second thought, your wheels would probablly not be spinning either way as to power said conventional "mouse trap car" one would generally use a string wound around the rear or frontal axis. without said friction, said string would not attach to said axis. basically, you fail, at life and beyond. As observations contradict this thought experiment, the assumed lack of friction cannot exist. Thus, friction acts upon mousetrap cars and upon your thick skull as information is shoved upon it.

no it does not
Static and Kinetic :)
ball sack
Slows it down
F1 cars need friction for their brakes, if they didn't have friction on there brakes then it wouldn't be able to brake.
no it does not
surface friction and sliding friction
Static and Kinetic :)
the first one is surface and a stick underneth it
yes
ball sack
yes
Slows it down
Yes, it keeps them on the road.
friction, air resistance and gravity

Cars don't get better gas or mileage.
