havnt they been proposing something like this for the last 10 years?i love the "you can fairly safely do 78mpb(10%+2mph) and escape conviction".i got dont for 33mph in a 30 zone so this isnt always true but as i once got let off for just under 100mph(at 3am on clear motorway) cos the cop had a coupe
i cant complain too much and speeding is speeding.tbh if they are going to 78mph they may as well set it at 80mph although that puts us inline with france ect who have 130km/h(78mph)limits but we have mph speedo's
