# What is the “comfortable” acceleration in a curve and braking in a car? [closed]

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 ...

• This question does not appear to be about physics within the scope defined in the help center.
If this question can be reworded to fit the rules in the help center, please edit the question.

• 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. – DanielSank Sep 24 '18 at 5:51
• I'm voting to close this question as off-topic because it's about human behavior, not physics. – David Z Sep 24 '18 at 6:25
• The question is due to a new car simulation that needs to reflect a real-world condition on a human body. – 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 $$2.55g$$.
