A car that makes a curve or a braking will naturally have its horizontal G-Force altered according to its speed and the intensity of the braking or the angle of the curve.

My question is: which acceleration / G-Force could be considered comfortable, especially for passengers?

When I say "comfortable" I mean a normal day-to-day driving, like a mother taking her children to school ...

    $\begingroup$ Just FYI, while this is an interesting question, it's like to be voted as off-topic since it's more about what humans like as opposed to something intrinsically about physics. That said, I think a truly good answer would explain why the preferred acceleration curve is the way it is by linking the human experience to something physical. $\endgroup$ – DanielSank Sep 24 '18 at 5:51

  • $\begingroup$ The question is due to a new car simulation that needs to reflect a real-world condition on a human body. $\endgroup$ – Rogério Dec Sep 24 '18 at 14:23

From Wikipedia's article on the order of magnitude of the g-force for various activities, unless you find roller coasters comfortable, the maximum comfortable acceleration is between $1.55g$ and $2.55g$.

  • $\begingroup$ Thanks. Just a beginner question: Is horizontal gravity (the stationary car) 1g or 0g? $\endgroup$ – Rogério Dec Sep 24 '18 at 14:19

    $\begingroup$ @RogérioDec stationary car is 1g. You'd need a vector sum for other accelerations. $\endgroup$ – Allure Sep 25 '18 at 0:19
