Re: Why now
People started return to work after the holidays, in many cases for the first time since Coronavirus kicked off, so traffic was back to 90% of pre-pandemic levels.
This meant that the driver shortage, which was previously hidden by the pandemic, became a problem.
By the way, there were shortages before it hit the news, not quite as bad as now, bit it was getting worse.
As for the long queues. There is an element of panic buying, but it is mostly people who normally buy from the empty petrol stations going elsewhere to find petrol. On my route to work, I go past 10 petrol stations that are visible from the road I take. 9 of those were empty last time I went in, and the other only had petrol in 2 out of its 6 pumps. That petrol station had long queues, but not 10 petrol stations worth of queues. Probably more like 3 or 4 stations worth.
