There’s another possibility - perhaps there was indeed significant congestion at the tunnels but it could have been clearing. As you approached the M25 it was quicker to go the long way, but by the time you’d actually joined the clockwise carriageway and started to go the long way round the traffic had cleared a bit.Sent from my VOG-L09 using Tapatalk
Mine often does that, sends me off to some roundabout, when I could have gone straight over, it seems to happen alot in South Wales for some reason!!!
