Roundabouts aren’t always efficient
Re: Best traffic-calming plan depends on where you are, Dec. 21.
Brigitte Pellerin’s advocacy for more roundabouts does not take account of European experience with them.
Roundabouts were very efficient when traffic was less dense. Europeans took to them to the extent that a much larger proportion of cars remained standard shifters, due to the fact that cars did not have to come to a dead stop, as they must with traffic lights.
