Yeah, why would you want to do that? Very strange.
I looked at the Wikipedia page on it. It seems like you would have a lot of fender bender and worse accidents.
Imagine trying to traverse one of those during a massive rush hour traffic period.
Where do these people (idiots) come up with these strange ideas?
Do you get the irony? A monument to the predecessors of GANG-GREEN Europeein EnvironMentalists being replaced by a stupid round-a-bout???
