When you live in a part of the country that gets a good amount of snow, you'll know what a mess that makes in your garage. All the crud from the days drive melts and falls off over night, and it isn't as pure as new fallen snow.
What we need is some way for the melt off to not mess up the garage floor.
How about two large rubber "boots" on the garage floor to drive onto and park each night. Not something to go under the whole car, just around the wheels and wheel arches. They would need to be longer than the wheelbase, and probably about twice the width of the tires, about 2 or 3 inches high.
With the car parked on them, the melt would all collect in the boots overnight. You simply empty them outside as required, with no mess on the floor.
