Speed Sensitive Steering Module?

[coolhandcountry]

For a few hi speed trucks. I adjusted my radio to do sort of like that.
I had it so the first part of steering was slower than the last. So if you move the wheel 10% it may only move the tires 5%. It made up for it later in the
Travel of the wheel though. Then again you not worried about percise movement in a tight turn situation. It made a big difference in how it drove
and handled. I can't think of what it is called right off top my head.
