All Sapphire drivers get additional customer training too.Back in my working past I was responsible for vehicle testing - meaning drivers driving set routes (and tests) to see how the vehicles performed and survived.
One such test was a flat-out high-speed test on a banked track to ascertain engine durability on continental roads (Britain having a 70mph speed limit whereas places like Germany didn't).
Some drivers relished the work and saw it as 'sport' whilst some drivers wouldn't push the vehicles as they considered it to be dangerous should a tyre burst.
I wanted to 'grade' the drivers to avoid having sessions where the vehicle wasn't being run to its limit, (and, even, reward the fast ones with a financial bonus) but the foreman (who allocated the drivers) wouldn't hear of it and insisted that each driver be given a turn.
