We've had the police helicopter over again - it looks as though there's been yet another crash on the M1 between Junctions 21A & 21 southbound.
This four lane section of road is seriously dangerous.
I only use it once a week and always stick to lane one and only use it between those junctions.
The design of the road isn't great - the services exit lane is just before the J21 exit, and the A46 traffic joins at J21A not that far before the entry to the services. However, lane discipline is appalling with a lot of drivers exiting J21 from lanes 3 or 4 rather than queuing in lanes 1 & 2.
It needs a combination of a 50mph limit and/or the services being closed southbound and/or a longer, barriered exit lane for J21, and/or banning HGVs from lanes 3&4 in this section.
None of which will happen until there's a very serious incident (which is certainly going to happen)
