I agree with Brian that cars parked on that bend are at a bit of a risk - but only if drivers are going too fast. The problem is drivers' speed, not parked cars. Generally speaking, parked cars slow down traffic so I would not want to see that bit of the road with yellow lines....that would just encourage traffic to go even faster.
I noticed today that Mayow Road is going to get speed humps. Good luck to the people who live there, Mayow Road needs them.......but so does Perry Vale! I went to the 1st Perry Vale Assembly over a year ago, and the overwhelming priority at that meeting was for traffic calming in Perry Vale and Perry Rise. A year later and......nothing, apart from the few bits up by the station.
If Mayow Road can get traffic calming, why not Perry Vale?
