East Renfrewshire Roundabouts (A727)
It seems like the East Renfrewshire council are looking into improving the Spiersbridge and Eastwood Toll roundabouts. My instinct is to go for safe Dutch roundabouts (not the bike-priority Dutch roundabout), it'll be easier to understand for British car drivers anyway.
Thought's are welcome before I draw in fiddly lane markings.
Eastwood Toll Roundabout:
The crossings require islands between each lane with enough space to fit a bicycle.
You should only ever have to cross one lane at a time.
