If you drive your vehicle, then park, and leave your vehicle without the hand brake, the vehicle moves and kills somebody, then it's your fault, and it's a crime, because your action - or inaction - killed somebody. From a criminal standpoint, the last driver - and only the driver - will be liable.
OTOH in this case it was somebody else committing the infringement, be it civil or criminal. For each, there's a procedure. Here, it should have been the driver - not the owner of the car! - the one who got a fine. It's a personal responsibility of the driver, not an "objective one" for the vehicle.
There's simply no mean, in most laws of any state of the world, for which such a responsibility could be transferred from who does the act to the one who owns something which is employed to commit such act.
Imagine you've got a knife, you lend it to somebody for some legit use, and that person commits an homicide using it. Are you a killer?
Speeding is an infringement committed by whoever speeds; the vehicle's owner has nothing to do with it. The whole "automated traffic control" systems were started with the wrong foot, without a proper legal basis.
