Do you require rolls for absolutely everything? Like even just driving out of a parking lot? I, personally, would save the driving rolls for extraordinary situations like a chase or trying to handle a vehicle with the brake line cut or the like. To my thinking normal driving shouldn't carry the risk of crashing every 20 feet as that would both be, not particularly fun, and not a very good simulation of the source material.
I mean the story is humorous to read...but I feel like you are perhaps letting the dice get in the way of the story a bit.
To each his own I guess. If the group enjoyed it then you are doing it right.
