18 year old lgv drivers

‘… I … need to ask professional LGV drivers their unbiased opinion on 18 year olds driving artics…’

I’m wondering what is wrong with having bias? Surely it represents opinion needed to achieve overall objectivity of an issue?

Anyway, why should the chance of achieving/proving an accountable quality of learning for (& passing a) test be restricted to those achieving little more than the arguable nonsense of an often meaningless numerical quantity? I was still as stupid at 30 as I had been at 18.

However, are we shying from a reality whereby those able to submit to test at age 18 are most likely to be socially/financially advantaged, ie, have a rich mater & pater - which might upset some seeing similar disadvantage nobbling kids from the humble mainstream?
