Red P's Mean Nothing
Fine, you've passed a driving test, but that's all you've achieved. Now you have to learn how to drive and that is a life-long undertaking. Two things, you have indicators and they clearly work, so USE THEM!
Secondly, you DO NOT stop in traffic simply to allow two pedestrians to cross a road when there is NO PEDESTRIAN CROSSING!!!
A little courtesy is a lovely thing, IF it's applied correctly. It can also cause trouble. This is a prime example of exactly why Red P Plate drivers become involved in more road accidents in their first 6 months than any other licence class.
