Think more like "I can be really distracted and suddenly swerve because my toddler threw their drink at me".
Like with L-plate drivers. Be very careful, don't hate, they're just danger to themselves and everyone else around. They're not entitled, they're warning.
You either are road-worthy driver who can drive safely or not. L ones are an approved exception and the list and law and expectations ends right there.
Nobody is babysitting 27 categories or potentially distracted or otherwise dysfunctional drivers. If you can't drive safely either have somebody else drive, use public transport or stay home. No excuses, you can very easily kill people including your own kids.
Becoming a parent brought upon quite an increase in my empathy for other parents.
* don't do this
What's more, notwithstanding the freakouts from Europeans and blue-staters about so-called "gun culture," you have no right to employ a firearm anywhere in the US unless someone is actively threatening to kill or maim you or a person near you. Not because you got in a road-rage pissing contest.
If anything, bringing a gun into a situation like that is a great way to get a felony assault/brandishing charge and lose your ability to own a gun period.
