On the one hand, human drivers frequently exceed posted speed limits. But allowing self-driving tech to ignore speed limits feels wrong somehow. Though it's better than your car snitching on you if you speed. Edit: From an implementation perpective, this should really be a percentage. 10 km/h is only 10% over the speed limit at highway speeds (typically 100 km/h in Canada), but quite dangerous in a school zone (30 km/h) or on a 40 km/h residential street.
