Of course, you would be angry. But is it worth it to start shooting the other guy? What if he shoots you?
I say, let it go. I subscribe to the belief that one way or the other, the ignoramus will pay for what he's done -- if not in this life, then in the next.
I do, if I can. I really don't care about parking spaces or mere acts of inconsiderate people. But I don't want to enter the next life because some idiot isn't paying attention, deeming what is going on on their phone to be more important than the trajectory of the two tons of metal they are supposed to be operating. That doesn't mean I go shooting people or seeking confrontation, but I'll report them in a New York second. In the meantime, my focus is on the health of the people with me and keeping my vehicle intact (avoiding, if possible, a wreck--I do not consider vehicle damage or injury resulting from gross negligence or seriously bad driving to be an "accident".)
Note, too, that the media reports this incident at the Trump Resort when it actually occurred at the Rental Car place across the street. THat's about in keeping with their policy of reporting any shooting within a half mile of a school as a school shooting.
