1. אותו כביש, אותה פנייה: הנוסעת מאחור מקבלת בחילה, והנהגת פחות.

   • doi.org

     Schmidt et al. 2020 (Transp Res F 71:76), accepted manuscript p.9 §3.2 and Fig. 3 (checked): carsickness in the last five years: back seat 46.4%, front seat 36.7%, car driver 17.2%. Lackner 2014 (Exp Brain Res 232:2493): drivers are generally believed almost never to get sick while passengers may, and evidence supports this.

2. באוזן הפנימית יש קריסטלים זעירים על שכבת ג'ל, ושערות של תאי חישה נעוצות בג'ל מתחתם.

     OpenStax Anatomy and Physiology 2e §14.1: hair-cell stereocilia extend into a viscous gel (the otolithic membrane), topped by a layer of calcium carbonate crystals (otoliths). Koch 2018 (Dtsch Arztebl Int 115:687): otolith organs respond to linear acceleration because the membranes are weighted by calcium carbonate crystals. Walther 2016 (HNO 64:767): otoconia about 10 µm, >90% calcite.

3. בכל בלימה ופנייה השכבה עם הקריסטלים זזה, והאוזן מדווחת שאנחנו בתנועה.

   • pmc.ncbi.nlm.nih.gov

     Koch 2018, 'Explanatory models' (full text, agent): the otoliths (saccule, utricle) respond to linear acceleration. Bertolini & Straumann 2016 (Front Neurol 7:14), car section: the provocative stimulus in road vehicles is low-frequency horizontal linear acceleration, fore-aft (braking, accelerating) and lateral (curves) about equally; the otoliths cannot tell gravity from acceleration.

4. העיניים על מסך שלא מראה את תנועת הנסיעה.

   • pmc.ncbi.nlm.nih.gov

     Lackner 2014, 'Much motion sickness goes unrecognized' (full text, agent): reading or looking at anything stable inside the vehicle requires suppressing the eye reflexes the vehicle motion triggers. Schmidt et al. 2020, Introduction §1.2: visual-vestibular discrepancies such as reading a book or watching a screen in a moving vehicle can make carsickness considerably worse; §3.4 Fig. 7: device use rated likely to cause carsickness by 61.7% of carsick passengers.

5. לפי ההסבר המקובל, הפער בין מה שהאוזן מרגישה למה שהעיניים רואות יכול לעורר בחילה.

   • frontiersin.org

     Bertolini & Straumann 2016, 'Theories on Motion Sickness' (full text, agent): the sensory mismatch theory is the most widely accepted; conflict = sensed vs expected information. Also Leung & Hon 2019, Zhang 2016, Koch 2018, Golding 2016. Limits: Lackner 2014 abstract (checked): no fully adequate theory is presently available.

6. בחיל הים בחיפה סובבו שניים יחד, ורק אחד שלט בסיבוב. מי ששלט הרגיש פחות רע. לכן השליטה של הנהגת עשויה לעזור.

   • arnonrolnick.comתומך בחלק מהטענה

     Rolnick & Lubow 1991, 'Why is the driver rarely motion sick? The role of controllability in motion sickness', Ergonomics 34(7):867-879. FULL TEXT READ (author-hosted scan, pp.867-876, 25.10.2026). Rolnick: Motion Sickness and Human Performance Laboratory, Israeli Naval Hyperbaric Institute, Haifa; Lubow: Tel Aviv University. 44 males aged 19-25 with sailing experience, randomly assigned, 22 yoked pairs on one two-seat rotating platform; helmets linked by a 71 cm rod so heads moved together; left-seat subject controlled direction, speed (max 11 rpm) and stops with a joystick, the passive one also had a joystick; both heard the coming stimulus over the intercom (predictability equated). 6 min with head tilts every 15 s and 4 stops. Mean symptom score 1.7 (control) vs 2.3 (no control), t=2.05, df=42, one-tailed p<0.05; well-being declined more without control, F(1,42)=24.01, p<0.001; 5 of the 7 who asked to stop had no control.

7. הנהגת גם רואה את הכביש; כדאי לנסות להניח את הטלפון ולהסתכל על הכביש.

     Irmak, Pool & Happee 2021 (Exp Brain Res 239:515), full text read by Codex: real car, rear middle seat, closed road, intense slalom; 18 completed both conditions (counterbalanced); mean sickness over exposure 4.2 with outside vision blocked vs 2.3 with it; 66% vs 33% reached moderate nausea. Turner & Griffin 1999 (Ergonomics 42:444, abstract checked): about 3x less illness with a very good view of the road (12.7% vs 34.6%). Griffin & Newman 2004 (abstract checked): a forward view reduced sickness; a live video of the road did not. Kuiper, Bos & Diels 2018: a display at windscreen height caused less carsickness than at glove-box height.
