just an idea, maybe a bit naive

I live in an area where car drivers aren't the best. Would this be a practical idea...
Those who drive recklessly (not necessarily breaking laws but putting people in danger e.g. instant braking, cutting corners, dangerous manoeuvres, not maintaining distance, general bad behaviour) can be reported for their behaviour by experienced driving instructors during day to day driving? Perhaps these instructors could work part time and, if during driving lessons or during normal every day driving, they encounter a dangerous driver, they could have special recording technology to record an incident, take a photo of the number plate and report it to higher authorities? A body could be set up to review these recordings and take action. If many such recordings are submitted and approved for a single driver, action could be taken? Perhaps some of the general public too who are experienced and have a clean record could be given this power. Of course, those submitting such recordings could also be judged as to how reliable they are. Perhaps this could be a sort of part-time job for many people who may want to do it for an hour or two a day? The pay wouldn't have to be significant as it's likely people would do it whilst every day driving and others may just not want bad drivers on the road. Could this work?
