Backseat driving is officially the most irritating passenger habit for American drivers, according to new research.
And most drivers can only put up with passenger annoyances for thirteen minutes on average, results show.
The research from Guessing Headlights pinpointed the top 30 passenger acts that annoy a driver most and found that, whether it’s offering unsolicited advice, opinions on directions or which routes to take or throwing out subtle critiques on speed and driving style, backseat driving is unanimously the worst.
Leaving trash behind in the car, complaining about the driving, eating food (especially if it stinks), and saying ‘watch out!’ when there’s nothing wrong were voted the top five ways to grind a driver’s gears.
Other prominent things guaranteed to ensure you never receive a lift again include changing the music without asking, putting feet on the dashboard, and not offering gas money.
Commenting that a driver’s riding the brakes too hard, pointing out the speed limit continuously, and bringing a pet without asking also made the top 30 annoying passenger habits.
And while many drivers are exceptionally patient, there’s only so long things will go on for before someone has to point out the behavior, according to the study of 2,000 Americans.
People can officially put up with an annoying passenger habit for 13 minutes (13.2) on average before feeling the need to say something.
Although a fifth (22%) will mention it almost immediately, pointing out any irritation in the car in three minutes or less.
The Guessing Headlights poll found that half of those questioned (50%) will mention it in under 10 minutes.
While an exceptionally patient one in four people are strong and silent, saying they’ll never mention it, no matter the duration of the car journey.
Interestingly, patience levels increase the older a driver is, suggesting experience goes a long way. Just 16% of Gen Z would let irritating behavior go unmentioned, rising to 19% of millennials.
A more patient one in five (21%) of Gen X would not comment on behavior in the car that they found annoying.
While 30% of boomers, nearly twice the number of their youngest counterparts, would stay tight-lipped and ignore annoying behavior in the car completely.
