Fanatic
Maybe you've met some blokes in the past who literally put a flashing light on their vehicles and pretended to be a member of a 4x4 response group, but weren't actually signed up members? From what I can tell 4x4 response groups are professionally run and linked to the emergency services.
It would seem unlikely that people who are kind enough to volunteer (at their own time, finances and personal safety) are annoying ego driven people.
E.g these groups that look well run and are registered charities:

Maybe you met a bad egg in a generally good spirited environment.
I'm sure members of the public are glad to see a volunteer turn up in heavy snow/flooding and pull their car out of a ditch, all for free!
