Roundabouts are too tight

THE big problem with the SDR is the roundabouts are too tight.

This causes cars to almost stop or change lanes and lorries to take a line that is dangerous as it can lead to the lorry cutting up cars. The problem is a design issue, with the entry and exit roads forcing traffic into the tight line. If the central reservations on entry/exit roads were wider, then the turn would be a lot softer and the chance of a capsize less. This would also increase the speed of the traffic using the roundabout(useful if the M4 is closed). Both my brother and I spotted this shortly after the SDR was opened.

the problem isn't the roundabouts are to tight it's more because all of the SDR road is two lanes but most of the roundabouts are three lanes leaving the middle lane of traffic on roundabouts nowhere to go.
And the Nash Road roundabout that's gone from round to oval is totally stupid

In actual fact it's the opposite problem: Travelling westbound at Maesglas East the two-lane road opens up into three lanes just before a two-lane roundabout. The same thing happens at Maesglas West. This forces right-hand-turning traffic and straight-on traffic who have just been separated to instantly merge back together again.
