I commute 100 miles a day and in my opinion its people driving too slow!
For some reason when it gets dark the M1 avg speed drops from about 80-85mph to 60. People drive about 3ft from each others bumper, they swap lanes constantly, and people constanly dab their brakes.
Its only so long before an accident happens!
In the summer when the avergae speed is higher, people tend to stick more to one lane, the gaps are bigger etc etc.
“Early early- seems to be more chilled motorists. EVERYONE is tired at this time of year regardless of am commute time IMO. “
Disagree the people up early are the ones who want to get there quickly. They are much more alert, drive quicker and have much better lane discipline, using their indicators etc etc.
When I leave at 6:30 am its fine. If I leave at 7:30 the standard of driving is shocking.
