Single lane traffic opens up to two. Pump stays left so I go to overtake. As I do this & cut level, Puma decides they also want to overtake what's in front of them but doesn't bother to MIRROR-SIGNAL & instead cuts straight to manoeuvre forcing me to then shift right even more. Luckily no cars coming our way.
Total maniac weaving in and out of traffic when all lanes are moving at 50mph in -2 degree temperatures on M40 south on 2nd Dec. Do you really think it is worth endangering other road users. You are only going to gain a few seconds
Upset i passed him filtering enjoy the wait in the traffic :)
