You know how there are people in life whose actions you don't understand - murders, rapists, paedophiles, people who want to pick a fight and hurt the innocent for no apparent reason? And you know how you meet well meaning but really stupid people too? Well, these people also drive of course.
Now then, does anyone imagine for one moment that their personality changes when they get behind the wheel? (Rhetorical)
So then, I hope we are agreed that these very same personalities are a problem on our roads just as they are a problem elsewhere in life. The difference is, they are not singled out on the road from the rest of us by the use of speed cameras and so the dolphins get caught with the sharks - it's that simple.
As Rigpig might say - a personality detector, that would be really useful
