I mean, if you want all your roundabouts to be demolished by semi trucks and other construction vehicles. And the price for the transportation of goods increased due to increased damage to trailers and the semi trucks themselves.
Personally, I love roundabouts. They're fun to drive around. But I have seen (and there's lots of reports about) semi tucks crawling over them at 5mph or less because they're all built too small to support a semi with a 50' trailer.
My vote is, once we eliminate the need for Semi trucks for deliveries in the city, sure. Roundabouts everywhere. But until then, let's keep infrastructure sane for all the users of it.
I suppose you could make the inner part something safe and non destructive to drive on but still uncomfortable so trucks could still make it through. Maybe Make rumble strips? Still have a structure in the very middle to prevent head on crashes though.
Most roundabouts have a very short skirt around the middle island thats like 10 feet wide just for this reason. Theres a curb so normal cars don't go on it, but it allows wide trailers to cut over them just fine.
They do indeed. And those still damage trailers and require semis to slow way down. The aprons also get damaged by the heavy trailers since they're not built to the same standards of roadways.
