Adam277, (and anybody else who might) please don’t take this the wrong way, I’m not putting the topic down.
I shouldn’t worry about a driver shortage, it would be brilliant news, but it’s unlikely to happen. There isn’t one, and there never has been, a study of driver salaries for the last hundred years or so will prove that.
I would be more concerned about some half-witted government scheme (if enough employers and trade associations shout loud enough) to encourage/force people in other jobs or on benefits to become HGV drivers. Couple that with “flexible working” (employer subsidies through “tax credits”) and we will really have some problems.
Look at the “wanna drive this bus?” adverts and see how bus drivers behave.
Look at the laughable “private hire” vehicles and how they’re driven.
Look at “self employed” food delivery drivers and how they act.
That - should it come, will be the time to start worrying.
