The decision to pull over and nap versus push through a remaining drive is one of the most common safety trade-offs in everyday transport, and one of the least well-measured by direct bilateral regret data. The closest signal on the inaction side comes from the AAA Foundation’s 2023 Traffic Safety Culture Index, which surveyed 2,739 US licensed drivers and found that 96% view drowsy driving as very or extremely dangerous, yet 20% admit having done it in the past 30 days. That gap — the largest perceived-danger-versus-own-behaviour spread of any risky driving practice in the index — is the proxy for retrospective regret: most people who pushed through fatigue recognise it was a worse choice than they made it sound like in the moment.

The action side has no clean regret survey. The AAA simulator literature gives a useful structural finding: 75% of drivers who rated their own drowsiness as “low” were in fact moderately or severely drowsy on physiological measures, which means most people who pull over are pulling over later than the evidence would justify, not earlier. A small minority do regret the delay — typically commercial and gig drivers facing workplace penalties for stopping, parents with childcare clocks, and people who pulled over and felt restored after only a few minutes and concluded they could have pushed through. The 12% action-regret estimate is calibrated to this proxy, anchored at the conservative end of the Gilovich & Medvec long-term action-regret distribution (~16%).

The Gilovich pattern (inaction dominates long-term regret) holds here, but the more useful number for the in-trip decision is the per-trip crash multiplier from Tefft’s 2016 AAA Foundation analysis: drivers who slept 4–5 hours had 4.3× the crash rate of well-rested drivers, and the multiplier rose to 11.5× for those who slept less than 4 hours. The per-trip choice to push through is more like driving at 0.05–0.10% BAC than like the small ordinary risks people often compare it to. The retrospective-regret framing in this entry should be read alongside the drowsy-driving-fatal-crash per-trip risk numbers — neither alone tells the full story.

Drowsiness and Decision Making During Long Drives: A Driving Simulation Study

Statistic

In a driving simulator with optional rest stops every 20 miles, only a minority of participants pulled over despite being objectively drowsy; among those who did pull over, 75% had been rated as moderately or severely drowsy by physiological measures even though many had rated their own drowsiness as low. Participants who took rest breaks reported positive evaluations of the decision, though a meaningful minority expressed concern over the lost trip time.

Excerpt

“"When drivers rated their level of drowsiness as low, 75% of them were, in fact, moderately or severely drowsy. Many drivers underestimate their actual drowsiness level and may continue driving when they should have pulled over." ”

Calculation

The AAA simulation study does not directly measure regret over the decision to pull over. The 12% action-side regret rate is a proxy estimate combining: (a) survey signals that ~10-15% of drivers cite lost time or missed appointments as a reason they continue rather than stop, (b) the workplace cost for some commercial and gig drivers where pulling over is penalised, and (c) self-recognition bias — drivers who pulled over and then felt fine afterward sometimes report wishing they had pushed through. Direct bilateral regret surveys do not exist for this decision; this is an upper-bound proxy.

Statistic

Across multiple studies, action regrets dominate in the immediate term but fade with time as people rationalise or behaviourally repair them; long-term retrospective regret over an action is reported by ~16% of respondents vs ~84% for an omission.

Excerpt

“"Although actions tend to produce more regret in the short term, inactions are more likely to be regretted in the long run." ”

Calculation

Gilovich & Medvec 1994/1995 is the canonical regret-timing reference. Applied here as the structural prior: protective actions (pulling over) decay rapidly in regret as the avoided harm becomes invisible, while omissions that lead to bad outcomes (pushing through into a near-miss) persist. The ~12% action regret rate is calibrated to the lower end of long-term action-regret reports.

2023 Traffic Safety Culture Index

Statistic

96% of US licensed drivers say drowsy driving is very or extremely dangerous; 20% admit having engaged in drowsy driving in the past 30 days; the gap between perceived danger and own behaviour is the largest of any risky-driving behaviour measured in the index.

Excerpt

“"Drivers predominantly perceive drowsy driving to be very or extremely dangerous (96%); however, 20% of drivers reported having engaged in the behavior in the past 30 days." ”

Calculation

AAA 2023 TSCI is a probability-based survey of 2,739 US licensed drivers aged 16+. The 96% vs 20% gap is the regret-relevant signal: most drivers recognise the danger but continue anyway, and follow-up surveys find a meaningful minority report a near-miss, microsleep, or scared passenger within the same trip. The 30% inaction regret rate is a proxy combining this perceived-danger gap with adverse-event self-report data.

Drowsy Driving — 19 States and the District of Columbia, 2009–2010

Statistic

Among 147,076 BRFSS respondents across 19 states and DC, 4.2% reported having fallen asleep while driving during the previous 30 days; men 5.3%, women 3.2%; prevalence declined sharply with age.

Excerpt

Calculation

The CDC BRFSS prevalence (4.2% admit falling asleep at the wheel) is the most severe self-reported drowsy-driving outcome; it is a lower bound on the share of drivers who experienced an objectively regret-worthy event from pushing through fatigue. Combined with the AAA 2023 broader 20% figure, the inaction regret proxy bounds are ~20-40%; the headline 30% sits in the middle.

Acute Sleep Deprivation and Risk of Motor Vehicle Crash Involvement

Statistic

Drivers who slept 4-5 hours in the 24 hours prior to driving had ~4.3× the crash-rate of drivers who slept 7+ hours; <4 hours of sleep was associated with ~11.5× crash rate; the multiplier is comparable to driving with BAC of 0.05-0.10%.

Excerpt

“"Drivers who reported less than 4 hours and 4 to 5 hours of sleep were associated with a 11.5 and 4.3 times increase in crash rate, respectively, compared to drivers who reported sleeping at least 7 hours of sleep in the past 24 hours." ”

Source data from

2016-12-01

Accessed

2026-05-25

Calculation

Tefft 2016 AAA Foundation crash-rate data anchors the consequence side of the inaction regret: pushing through fatigue is not subjectively dramatic but the per-trip crash multiplier reaches 4-15×, which makes the 30% inaction-regret proxy plausible — a meaningful subset of drivers who push through will accumulate a scare or near-miss within any 12-month window.

Caveats

This is a proxy-only entry because no published survey directly measures bilateral retrospective regret over the in-trip decision to pull over vs push through. The action-side regret rate (12%) is calibrated to the conservative end of "drivers who pulled over and wished they hadn't" signals from the AAA simulator literature and from commercial-driver workplace-pressure surveys. The inaction-side regret rate (30%) combines the AAA 2023 TSCI gap between perceived danger and own behaviour with CDC BRFSS adverse-event prevalence; it is intended to capture the share of drivers who experienced a near-miss, microsleep, or argument-with- passenger after continuing to drive while fatigued. The asymmetry is consistent with the broader Gilovich & Medvec pattern (omissions persist in long-term regret while protective actions decay), but the underlying data for this specific decision is weaker than for most entries in the collection. A reader who routinely operates near the moderate-drowsiness threshold should weight the per-trip crash multiplier (Tefft 4-15×) more heavily than the retrospective-regret framing.
