How to control the driver rotation speed?

Hi, i have a wheel rotation driven by an object moving forward, i want to be able to control the speed the wheel rotates in relation to the object moving forward. Is there a way of doing it in the driver settings? or maybe the animation nodes? Thank you in advance.

Sure, more than one way.

You could multiply the driver input by a constant-- for example, instead of using “var” as your scripted expression, use “var*0.5”.

Alternatively adjust the curve handles in the driver editor. If you drag the right handle down half way, it will only go half as much.
