The biggest problem with roundabouts the main direction can starve the lesser-used entrances.
Imagine the main road going North-South, and you're entering via East to go South.
Because of never-ending traffic going North-South you just don't get to enter.

- ifwinterco 2y agoNeither of these really solve the problem if you're trying to go anywhere other than the first exit. OP is right, this is an issue with roundabouts and you end up needing traffic lights in this case (at least at peak times)
- prmoustache 2y agoSometimes tunnels are builds to avoid lights when going straight is the direction favored by the majority but it can force an unwanted loop if you stayed on that lane and you didn't realize in time you had to go right to take the roundabout.
