Thanks for the replies everyone, so I tried driving my car yesterday night at 65km/h and I tested the lane keeping aid by letting go of the steering wheel and seeing what it would do (don't worry there was no traffic anywhere and my hands were still right next to the wheel so I could regain control whenever I wanted).

My expectation of the system is as the car drifted toward the white line, it should have torqued the wheel to put it back in line, however what had happened was the car just drifted half way into the other lane where I then took control of the steering wheel again to direct myself back into my lane.

I'm not sure whether night time visibility has anything to do with the camera operation, but it seems clear that the system isn't working at all.

The only thing I'm thinking is that the system might work best on highways where you are driving at a faster speed (say 100km/h+?) and that it wasn't meant to be designed for slower suburban speeds.
