Yeah, exactly what I want. My Corolla has all the options, but enabling disabling limiter is not easy (takes at least 3 button presses) and it would be cool to have programmable single-touch limiter.

I’m ok with the limit itself, I just want a dedicated button on my steering wheel to turn on/off 20mph speed limit.

In my childhood they used to have much better toys. Even whole series of cartoon characters.
