I've just checked out Walmart's bike collection online and compared to what is on offer this side of the pond you guys get much more bang for your buck.high end bikes that you'd want to hang on the wall as art or cheap imports that are uninspiring are mostly available here. I'd love to have the same big box options as Walmart offer because as long as your frame is sound the quality of ride is up to you.
as for Smart cars,check this crash test out,

I really like the Smart concept but,it appears if you crash one at speed you'd be lucky to survive as burger meat let alone a functioning human being!
