Self-driving cars need to bend the rules enough to be attractive to a critical mass of purchasers. Then regulations will require strict adherence to laws. Then owners of these cars will be numerous enough to push for regulatory reform. If all self-driving or driving assisted cars were limited to exactly the speed limit and following the letter of laws that no human follows, they will never achieve mass adoption. FWIW, cruise control has always let you set any reasonable speed. Doesn't quite seem right to hold a car to a different standard just because it's advanced enough to sometimes know the actual speed limit.
