A wave is not a green light

There’s a four-way-stop personality everyone has met: arrives first, then sits, waving everyone else through in a jam of generosity while the intersection quietly stops making sense. One spouse described cringing through it regularly. The community that discussed it has a harder name for the habit’s worst case — the wave of death — and enough wreckage stories to earn it.

The rule has two halves, and they protect different people.

Don’t give the wave

Never wave anyone into a road you can’t fully see — and mostly, don’t wave at all. The witness accounts are the argument: a driver waved through a gap cut across without looking and was hit in the next lane — a lane the waver couldn’t see either. A pedestrian waved across by one “nice” stopped car met the car that didn’t stop; she was lucky to walk away with only a broken leg. A city truck driver explained the quieter cost: a big vehicle needs a couple of circumstances lined up before it can move, and a stranger’s courtesy can’t see them — so the favor just adds pressure. Right of way isn’t stuffiness — it’s the shared script that lets forty strangers predict each other at speed. As one inherited saying puts it: don’t be polite, be predictable.

Don’t spend the wave

And never spend anyone’s wave as if it were your own eyes. The waver is usually sincere and always under-informed — they haven’t checked their mirrors for the illegal pass, the reversing garbage truck, the second lane. One person backed out of a driveway on a helpful stranger’s confident motion, straight into a truck the stranger hadn’t seen; the signaller drove away. Another’s neighbor pulled out on a passenger’s word that the way was clear — and was T-boned, her pelvis broken in multiple places. Take the wave as a kindness, return the smile — then look at every lane yourself before anything moves.

None of this cancels ordinary road grace. Easing off to let a signaled merge happen is cooperation inside the rules. The line is simple: courtesy that keeps everyone predictable is generosity; courtesy that hands a stranger your judgment — or borrows theirs — is a coin flip at thirty miles an hour. Take your turn. Trust your eyes. That’s the whole kindness.
