Think of the worst piece of traffic congestion you have ever endured in the UK. Finished? Well, there's a good chance that the black spot you have thought of was a stretch of the M6 in Birmingham from junction four to junction 11.

The trip should take 23 minutes but is regularly more than an hour and getting worse.
