The problem is that reckless and aggressive can only, it seems, be cured over many years and in the meantime how many lives are lost as a result of that behaviour.
without understanding of a traffic
The stats show otherwise. Stats show that it's actually women who observe the rules of the road and understand how traffic
shouldwork. What you're saying is that they struggle to cope with mens' behaviour in traffic such as overtaking on a bend, going straight through a junction or roundabout without a glance right or left, coming up the inside lane on a motorbike, lane hopping, no indicators, driving straight through a pedestrian crossing where somebody is waiting to cross.
As for hesitant and insecure that's a generalisation which certainly doesn't fit all women drivers but it can certainly be cured as can poor driving techniques. That's down to being poorly taught in the first place. If you get a good instructor and learn proper defensive driving skills you can overcome that. For example when I started driving I had a tendency which is very common in learners to 'wander' towards the centre of the road and out of lane. My instructor showed me a little trick of periodically checking my left hand mirror to monitor the position of the back wheel in relation to the line at the side of the road. There are times when you need to be confident in traffic and push ahead such as overtaking where you can't be faffing about, and there are others when you should be more cautious.
