Problem is people looking at what their sat nav is telling them and completely ignoring road signs and markings.
Similar to the roundabout on the A47 coming from Wisbech to Kings Lynn that intersects the A17; the r/h lane is marked up to turn right only, whereas the nearside lane is clearly marked ALL ROUTES. Obviously if heading towards Fakenham etc I use the n/s lane to turn right. I undertake some very upset people.
