This one would be perfect for G-ma to get to work. Little green pea car! Yes, can't you just see smooshed green pea car when some uncoordinated SUV driver "bumps" into it? Not good- cute and efficient but that is a bit of problem.
This is a design by: Andre Rumann. It is a simple little product that involves a keychain holder (being the garage) and a keychain in the shape of little mini car. So when you return from work, simply park the car (and your key) in the garage :)
