I have no idea how to report this so if there is any of our friends from Traffic on here:
Dip on the M40 London bound on the 3rd lane of 4. Location sign B38.6.
Its been getting gradually worse over the last couple of weeks and IMHO its getting dangerous and has the possibility of causing an accident.
Over and out, and to everyone else, not that you would do over 70mph but if you do be warned as its horrendous at 70!
