There is a shortage of well-paid driver jobs.
There is an abundance of low-paid driver jobs.
There won’t be a shortage of “drivers” - until and unless every COMBINED job vacancy across the two groups above - gets filled in due course.
Who will feel the pinch first?
I would suggest that those firms who would rather employ a “six-points OK” driver who “doesn’t argue the toss” rather than a clean-licenced driver who’ll always push back when wronged - might struggle to keep their internal overheads down, Eg. fixing numerous vehicles and property smashed up by the less experienced driver, who was “only doing what they were told, to the letter” all the time. 
How much money did “firm’s policy” lose from THIS little incident for instance?
Sunak in his Spring Budget - might decide to raise taxes indirectly rather than just lump extra income tax and national insurance contributions onto the masses…
ONE such way of “raising indirect taxes” - would be to reduce or abolish completely the way a firm can claim things like “damage to property” against tax…?
I’ve already spoken at length in the past, meanwhile - that INSURERS too - might one day decide “not to cover that firm who go out of their way to employ sub-standard drivers” that smash stuff up…
Now all that remains - is to see how many people can be shifted into 55-84 hour week jobs at or near minimum wage, should the day come soon when “at or near minimum wage” happens to be all that’s left out there.
