I'm probably more conscious than most of people declaring that ALL drivers over a certain age should automatically lose their licences, as I have a medical condition that, when well controlled and monitored, has no impact on your safeness to drive. If anything, we're possibly safer than drivers without the condition, as we know to be aware and cautious about our capacity at all times.
Nevertheless, a tiny minority of people with this condition have in the past not been responsible, with sometimes tragic results. Because of this, there are a great many people who insist that we should 'err on the safe side' and take away the right to drive from all of us.
It's a slippery slope, when it's not based on factual evidence and individual circumstances. We could say that nobody under 20, or 25, or 30 should be allowed to drive, as they lack maturity and general life experience. We could say that anybody who wears glasses can't drive, because there's a minuscule chance that they might fall off at the wheel, or one of the lenses become loose.
Parents of children under 8 shouldn't drive either, as they may well be distracted from driving safely by their kids. Anybody who routinely drives forwards on to their drive instead of reversing on is clearly not observing good, basic safety (as according to the Highway Code), so they need to lose their licences after three offences. People who live in big cities with excellent public transport shouldn't be allowed to drive, as they won't be doing it regularly enough to gain enough road experience and retain their road sense.
Anybody who originally comes from a country where they drive on the right and/or English is not an official language is an absolute no-no, as they might forget to drive on the left and won't be used to our signs, especially ones with writing on them.
Women should be banned from driving, as fluctuating hormones might affect their moods and make them emotionally risky, plus may also be pregnant and thus potentially suffering from 'baby brain' and/or be too big to fit comfortably behind the wheel; so best just be safe and leave it all to the men. Men should be banned from driving, as they tend to drive more erratically and faster than women, so best just be safe and leave it all to the women - whom we've already just banned..........
