Last night, coming back from the snooker, there were a load of 50-limit signs on the dot matrix displays between J5 and J4 on the M40. Turned out there was a Ka that had spun around and was facing the central reservation, taking out the middle and right lanes. I safely avoided it without any problems, but couldn't help saying to myself "where the f*ck are the police", thinking that it must have happened long enough ago for them to activate the 50 limits on the dot matrix displays. Then a little while later I see a police car on the hard shoulder, blue lights flashing, then I realise it's moving. Backwards. Quite quickly. Obviously very sensible compared to driving the wrong way down the hard shoulder and dazzling everyone, and I guess they decided to do what they did rather than drive up to the next junction and turn around because of the proximity of the RTA scene to J4.
But it got me thinking - how fast can those Omegas (I'm guessing it'd probably be an MV6) do in reverse, and are the police ones modified in any way for this very purpose?
