This is awesome mate and I do applaud your decision to pass any settlement, if any such is forthcoming to a charity. I wish you success and may you be the first of many on this road to taking money from them.
Just an idea, if many more are prepared to do this, maybe use any gains to perpetuate this by buying a few more banger's

maybe even have a banger rally all driving these around towns with loud speakers spreading the message

like the lorry drivers did protesting about fuel costs

I am actually thinking of doing this but, just taking my licence plates off completely. As from birth I have been deceived all bets are off. I think this is the most straight forward approach. Place the burden of proof on them and if they can't prove or produce then It proves truth. After all if you are deceived into consensual agreement, it is void upon discovery of deception surely.
It is just a matter of teaching them what there management have failed to teach them. And if we want it done properly, we have to take it upon ourselves to do it.
