I am miffed with this story while reading this post here, I was just watching the news with the cars hitting this makeshift bumper.
First, of all any standard type of car would be severely damaged if only one side is hit.
Second, the height of the impact was into the grill not the bumper below it.
Third, the reason behind the test is...? Who knows, but it's scare tactics like this that prevent people from even considering a smaller car.
Fourth, years ago the same test were made with American vans, etc. and the damage was in the thousands also at such slow speeds. The exception was the beetle which then cost $300 to fix.
Fourth, from the top view the makeshift bumper did not flex at all, unlike another vehicle's.
Finally, why do you need a solid bumper ? Unless you live in the heart of a city and there is no guarantee either. Your little car will be attacked from all sides then.
One more for the road... Did they crash 4 different smarts for example? If one smart hits something once, it is then compromised already when it hits the second time and gets worse with the third and fourth. Would someone enlighten me please.
