I had an autostarter/ 2-way on my SVX that I still kept after converting to manual. Had removed NSS so it could start without the clutch being engaged. NJ doesn't have anything in the much of safety testing anymore so that was fine. You do lose cruise control however.
It's arguably more dangerous with that route since you could start in gear by accident. Had it that way for about a year, then someone started my car with the remote by accident, and then the car rammed into the garage door.
