Road marking arrows shows straight on, too tight

The approach to the roundabout on Peterborough Road From Farcet at the Standground Fire Station has been re marked, left lane now shows left and straight on, before it was left only! the right lane shows right and straight on as before. There is not enough room for both vehicles to go straight on using both lanes especially when they try to exit the roundabout.. I believe this will cause confusion, congestion and possibility of road traffic collisions on this roundabout...I believe the left lane marking should be left only!.... I believe these road markings have been incorrectly marked as there is no notification to motorists on approach of lane marking changes.
