Once again it seems that any road closures that you're unaware of to start with cannot be reported effectively. Junction 5 exit of M1 Northbound. Reported at midnight myself and again at 1am. Google knew about it at 11pm apparently. But as of 215 am it's still open as far as you're concerned. How hard is it to spot traffic ignoring a major road and a corresponding notification that it's closed? And don't give me any rubbish about construction traffic confusing your system....it can't be hard to program the system to spot them. They start or finish at that road or very close by...or hang around inexplicably. Closures should only be cancelled out by traffic that is clearly through-traffic. It isn't hard to spot construction vehicles and how they behave differently.
