Where 20 mph zones have been introduced and enforced, all casualties have fallen by around 60%
That is due to the location of the 20 MPH zones. They are implemented in the vicinity of schools or housing estates where there is a high chance of children running out into the road in front of a vehicle. That situation does not come into play on the motorway and so the example is invalid in this discussion.
No one is against reduced speed limits with strict enforcement - when it is done for real reasons. However, enforcing the ancient 70 MPH limit on motorways is seen as many as simply money-grabbing.
MadMark!!!
