This thread made me think a bit; since it was first posted, I have paid attention to who is driving around me.
Low and behold, the better drivers have overall had gray hair or other indicators of age.
The ones taking big risks turnout to be youngsters slightly more male than female but the greatest gamble I saw was by a female.
The oblivious were in the majority. Defined as; pulling out at junctions into traffic seemingly unaware of others evasive action,
passing parked vehicles without slowing or moving out,
window shopping,
not correctly positioned on the road,
not using indicators when it would have helped all around,
not knowing who had priority at mini roundabouts,
smoking and driving these were mostly female. This body of motorists in the main were not old.
The next class were the bad tempered horns.
The victims were in general,
refusing to drive on the bumper of the car in front,
not racing pedestrians on crossings,
waiting for green or stopping on amber,
being sensibly courteous,
none of the horn players appeared to be elderly.
The worst and most thoughtless behaviour I found at school run times around schools,
in the form of silly parking,
driving close to parked cars,
opening doors without looking,
shouting to children across the road,
turning the car around with children milling about,
double parking,
driving off without making any checks. These were male and female mostly of breeding age.
I do not claim this was a scientific survey, but it passed time on several trips across town.
It is not my normal driving practice to bother with other driver’s behaviour in this way, I would adjust to what is going on and concentrate on driving my car, but it was quite surprising.
I think the issue is reasonably under control, police can stop and advise or enforce and or family members can and do intervene for the cases were people should not be driving.
