It already doesn't look wide enough to cope with demand.
And I if I see up to 5 on my route into Leeds it's a busy day.
Are those the lanes over Vauxhall Bridge (is that the right one?) that no one is using?
You do sometimes have to go at the pace of the pack. The people who struggle with that, overtaking, pushing in etc are a bit of a problem.
I wonder how long it will be before the road is so freed up that people will switch back to cars?
