> What if you don't know who drove it? (you might have borrowed it to a few friends but don't know who drove it when)
As someone else touched on: in most states of Australia, the owner of the vehicle (as per the registration) is responsible. If you "don't know" who was driving your car it doesn't matter-you are responsible for the vehicle unless you have reported it stolen. Which I think is fair: if you're going to lend your car out, make sure you trust the person driving it.
I feel that nailing the owner is completely unnecessary. The owner might be responsible for the vehicle but the driver is responsible for how it is driven. Parking tickets is a reasonable exception since it's hard to prove who drove it last. For your own sake you should always trust anyone you are lending your vehicle to but you shouldn't have to care for any legal implications that might result in (other than parking tickets).
In Egypt three speeding tickets means jail time (if I remember correctly), only not for the driver but for the owner. IMO that's just sick.
