Growing older hasn't lessen'd my impatience but has directed
me towards the high road (most of the time)

in these frustrating circumstances.
It is utterly futile and quite possibly foolhardy, to aggressively attempt to correct or punish a boorish, impatient or incompetent driver while in traffic. Given the steadily increasing occurrences of road rage confrontations, especially noteworthy here in North America, has also significantly contributed in forming my present-day attitude towards the matter. Best to take note of number plate and make a complaint
if you feel the situation warrants it.
