Are drivers required to use their blinkers when changing lanes in roundabout?
IMO the villages could manage the roundabout better by not planting shrubs and annuals that grow too tall and block vision of normal height cars. Course if you in SUV or truck your vision not hampered by too tall shrubs. IMO waste of money planting annuals at entry of roundabouts and very dangerous for the maintenance crews and traffic while doing this.
Why not just plant shrubs that don't grow too tall blocking vision when I look left to see traffic? the extra benefit LESS MAINTENANCE and COSTs. Course somebody going to say but it's so pretty. Give me break it will just as pretty with pretty LITTLE shrub

.
Certain percentage of vehicles and NOT going to yield to motorcycles due to they don't care or motorcycle/scooter in their blind spot.
