Suburban areas are probably the best place to go for your L Plates, primarily because the frustration of city traffic might force you to do something rash behind the wheel. Being from Penrith, I know that streets around Penrith are nice and calm during the time between peak hours, they are also long and straight and great for that suburban lack of frustration
I did my L's computer test at Liverpool RTA, (it has now moved to a new location and become Service NSW). I was placed right next to another candidate and disturbed by the noises they were making while I was trying to complete my test. I failed one question which meant I had to resit, this time at Wetherill Park where I passed.
