that is what i have yet to find.

NHTSA specifies that you must make it so that there is passanger protection from the steering. i.e. collapsable steering shafts so that you don't get impailed.

49 CFR talks about joint slop and steering input slop.

unless there is a state specific thing, i am very interested in finding a federal requirement. there does not seem to be one.

edit: this article talks about the infiniti Q50 that uses "steer by wire" https://www.wired.com/2014/06/infini...steer-by-wire/ and is road legal
