I have had RACV roadside since 18, nothing but useful, needed my first car broken into once for locking the keys in, needed a few jump starts, also had my old car towed once, but the best one was the alternator went and he patched it so i had a chance of getting home and if i didn't get home i'd at least be close enough to be towed for free, it died in the driveway!.
they are an assistance to get you off the roadside as everyone has said.
all 3 cars with them, they even gave me 3 months free roadside on my WM since my old car was written off and had issues transfering the write off car onto the new car details.
