Anyone who is able to drive a car 3rd party with owners permission. As long as everyone agrees, you give details of someone, saying you lent car to them, when that person gets the ticket, asking who was driving, he says someone else was using the vehicle, and so on, until the police get fed up and don't chase it.
As long as they can prove they have insurance to drive any vehicle, and you say they had permission, what can they do?
Obviously haven't tried this! But if someone wants to try it, let me know.
