Bad drivers

When you exit A45 Nene Valley way - the two left lanes are for the town, the 3rd land is for Rushmere road - hence if i come down A45 i exit on 2nd exit to be in 3rd lane.

I came down A45 from other direction and went right round roundabout to go Bedford road into town. An idiot driver just cut in front of me he was in lane two but wanting to go Rushmere road. This was a near miss, he should have gone down bedford road and turned round at a roundabout . Over last year I have seen at least 5 cars take this junction wrong and go right in direction of rushmere road. I waited until green light so suspect the driver who cut in front of me went through on red - if not lights not staying red long enough
