P-plate

at lunch time, when i was waiting at the lights, there was a taxi turning left at the junction, and it crossed from the far left lane to the right. the funny thing was the P-plate driver behind the taxi kept shaking his head... like he has lots of driving experience...

just wondering, if someone has an open licence more than a year, and has only driven like less than 10 times (like me?!), when this person is on the road, how many drivers will shake their heads??

thinking maybe the L-plate drivers are also wondering, how can this person get his/her licence...
