I always thought that carrying in certain places like airplanes and sporting events don't really need to be scrutanitized or disected nearly as much, as one carries there as they are between places where they are more likely to need a firearm. Same with carrying while driving. The chances that drawing/firing while driving would ever be the best thing to do are insignificantly small, but transitioning when you are stopped each time is not reasonable.
Yes, I know that there are chumps out there who fantasize about brandashing in such places to look tough, but I think that is likely a pretty small minority.
