The only thing that we can do is anticipate their behaviour and drive accordingly.
E.g.- if someone is attempting to overtake you in a dangerous location, use your mirrors, slow down and just let them pass.
E.g.- if a motorbike or sa-ling pulls out in front of you without looking, be prepared to slow down quickly and wait behind them until it's safe to overtake. It will only add a few seconds to your journey.
E.g.- If you see youngsters (or even boy racers) ahead or behind, give them a wide berth. Imagine the <deleted>storm you will face if you get involved in a fatal accident, even if you are not to blame.
Etcetera.
Sorry to come across as a bit 'preachy', but we need to apply our best standards. Maybe others will copy.
