actually the most stressful event everyday is driving.. wah lau, suddenly all the cars, taxis and big vehicles are 'snatching' road! sometimes want to change lane, the behind veh see got space, they just step on the pedal and 'snatch' the road!!
i tested this scenario before, as long as there is a gap on another lane, just signal towards it and within seconds the car behind will close up. on a dull day, i do it constantly to entertain myself, works all the time.
