its been bugging me for a while this one
speed limit signs on the roads ie 30, 40, 50 etc
have you noticed that if the signs are saying 60 the traffic is doing 40 and if it says 50 the traffic is doing 30 ?
it is dead obvious this one and was stareing me in the face - which probably expains why it took me so long to figure out
have a look next time this happens to your traffic queue
so what are you looking for ?
look at your speedo - not the miles per hour - look at the kph
60 kph is 40 mph , 50kph is 30 mph
so why - its easy when you figure it out - not all the drivers on our roads took their licence in this country did they ?
as a lot of other countries do all their speed limits in kilometers they are used to kph instead of mph
i had to talk to a few non uk drivers to confirm my logic and they agreed - so there you are , and now you know
