We don't have to put experimental on the side of EAA type aircraft in Europe (don't know about Africa, but I suspect a similar situation). All we need is a plaque somewhere in the cockpit. Experimental craft and IFR don't really mix here though, can you fly IFR in experimental aircraft in the US? Then again, at least in certain countries you wouldn't even need to do that for something like this. Depending on empty weight etc, it could well be a microlight/ultralight. Don't really see what the big deal is about this though, seen plenty of similar in the past. I think the flyke is cooler, actually. (http://www.freshbreezeusa.com/flyke.htm)

Here's how a SmartCar will fare against a brick wall: http://youtube.com/watch?v=ju6t-yyoU8s The problem is not that of the car breaking or not, it's how it manages to decelerate without subjecting your body to forces that it cannot survive. Many SUVs suffer problems in this department, because they are simply too hard. If you hit a brick wall with them, they stop, which might well kill you. Same with the SmartCar, but unless you really hit it straight on it's likely to bounce off in some direction, and then decelerate as it hits stuff. An SUV will probably not. On the other hand, SUVs are going out of style in the US in a big way right now, and will probably not be around much longer. Just check the price of crude oil from 2001 to the present day.
