FL, there's nothing wrong with being passionate about what you do and you obviously wear your heart on your sleave, however, is important that people see the bigger picture and take reasonable actions to achieve their aims.
In many situations there are many pathways that end up with the desired outcome, in this case a reduction in speeding resulting in fewer accidents and the resultant injuries, damaged vehicles and potentially deaths. However in my view taking a series of actions that result in both the perpetrator correcting his behaviour and remaining engaged in the processis a much better result than the course of action that appears to have been taken here.
As you have admitted you took your commission so that you could have had a bigger impact on a larger group of people yet you limit your team to those within your functional responsibility, yet this airman, for whom you would have some responsibility whilst he is in one of your vehicles, is seen as an outsider.
IIRC there's no time limit on taking actions for MAA, however, in my own opinion, taking into account the intent of the MAA process, I think it's unreasonable to use it for an alleged offence this old when management discretion would suggest another course of action more appropriate.
