Hi HJ. First time of posting after many years of avid reading! I've made several longish M1/M6/M40 motorway trips recently, and on each and every one of them the journey has been fouled up by a section of motorway being closed somewhere in the vicinity. From a trawl of your site and the ABD site I can see that this isn't new - but it seems to me to be happening more rather than less often, and it's surely not always because of a fatality/major public safety issue? Do I recall something about the 'criminalisation' of dnagerous driving and consequently a police incentive to gather evidence? Have there been successful prosecutions that would not have been possible without the evidence whose collection required the motorway to be closed?
