Depends on the size of the roundabout, some are designed for 40 mph others for a more sane 20 mph.

- Ntrails 10y agoI mean, a roundabout is a system for efficient "giving way". 20mph is only "more sane" when a roundabout is in a low speed limit area. We've got plenty of them on 60mph zones - you've got no interest in having cars slow down and accelerate again when not necessary (if nothing else because it's a waste of energy as well as time).
- arghwhat 10y agoHow is it efficient for "giving way"? If one entry is highly traficated, entries between the traficated one and the popular exits cannot get in.
