Have to agree that the title of the thread is wrong and misleading but that’s insignificant.
In theory it’s a brilliant idea, along with turning all stop lights to flashing amber between midnight and 5am to allow vehicles to continue – so long as it’s clear / safe to do so.
But, and it’s a full bodied but, people just don’t have the consideration that is required for this to work. The vast majority of road users – cars, pedestrians, lorries, cyclists etc… – don’t pay enough attention or even aware as to what is going on around them on the road. They REACT to the situation they’re in rather then planning and allowing for it.
Until there is a shift in attitudes of the majority, aware from inattentiveness, then accidents will still occur and, unfortunately, this proposal will just add to the KSI stats.
