Of course, this could only happen in Europe... in America our cars "need" luxurious two car garages with plenty of room to open both doors and still have enough space to keep the lawn equipment, Christmas decorations, and unwanted furniture along the sides.
I wouldn't advocate that we all have garages like this man, but his example shows just how compact we could really be if necessary. The question is: when will we Americans find the golden mean? Why is it that we are stuck on hyperdrive, demanding huge houses, huge bedrooms, huge garages, huge yards? When will we begin to emphasize quality over quantity?
