it the eyes of the law, both committed traffic offences. regardless, both lose lose situation.
Sometimes, better to take a step back, wave hand, smile and move on.....
Most likely outcome...
cyclist - fine for obstructing traffic
Driver - fine and ban for dangerous driving for inching the car towards, drive off with someone holding onto the car.
If such an incident happen to motorist (someone jump onto the bonnet), never drive off, straight away put car to park, pull up hand brake and call the cops...... there are video evident .....
but again, if in malaysia, remember do not stop
