When someone changes lanes with no signal, it feels less like driving beside a neighbor and more like sharing a hallway with a shopping cart possessed by a small demon. The maneuver may work out, but everyone nearby has to suddenly invent a backup plan.
A turn signal is not an RSVP, a force field, or a magical lane-reservation app. It is a tiny early warning: “I might move that way.” Give it a few beats, check that the lane is actually open, then make the move smoothly. Likewise, seeing a blinking light is a reason to pay attention, not an invitation to bet your front bumper on a stranger’s next decision.
Ordinary courtesy on the road is wonderfully unglamorous. Signal before the drama; leave space when you can; accept that nobody earns a trophy for winning the merge by half a car length. What small driving habit makes your commute feel noticeably more civilized?
