On speed limits to the letter in autonomous cars


cruise Control speed-adaptive: keeps the programmed rate until you find traffic, from there, follow the same pace of the others

What is going on with Tesla is a preview of a debate that will be in the not too distant future. autonomous cars, by definition, will comply with all rules of the circulation unless it is strictly necessary to rape them, as do a dodge to avoid an accident.

that Is to say, they would do the same thing that the more neat, and civic drivers. Human beings rarely have a compliance strict rules, even the people more aware they can make mistakes or omissions. This is not the case of programming and artificial intelligence, practically we talked about the 100%.

If there is no reason against it, shall comply with the rules

Will be an ideal scenario: cars passing right by them, respecting the speed limits, overtaking in a legal way, without assumption of any unnecessary risks… and that can be a problem with those who consider that their car can go a point beyond it.

that is why we return to the case of Tesla.


The first versions of Autopilot allowed you to dial in a cruise speed above the legal limits. The responsible would be in any case the driver, but Tesla understood that a bad press at the dawn of the driving autonomous (and that are semi-autonomous) would not be positive.

slowly, Tesla has been updating Autopilot -through the Internet, provided that the owner consented – to reduce the possibility of misuse. In the last update will only be allowed to exceed 5 mph of the limit (almost 10 km/h) on expressways, but not in the conventional. That has not liked thousands of owners.

therefore Tesla has had to go back and lift that restriction, while it has improved the system when used in ways not very appropriate, as the dual sense. Autopilot is thought of as a system for the highway, without intersections at the same level of circulation. The only fatal accident with the Autopilot occurred exactly at an intersection of that kind on the part of a driver is distracted, the car was not able to “see” a truck that crossed their path.


In theory, when you choose a driving mode 100% autonomous, in which the human being does not have to intervene for nothing (level 5 SAE), the vehicle must comply with all the rules of the road. Legally there are still questions of who will be responsible in case of accident.

just Volvo that has assumed the responsibility voluntarily, always and when their cars go in automatic mode. In any degree of driving semi-autonomous, the responsible is the driver human, more than anything because it is in the pyramid of decision making. In the automatic mode could be the manufacturer itself, but the laws are cooking throughout the world.

Will there be models that will enable the driver in automatic mode, you break the rules? For example, if we want to make a long trip and we’re going to cross a highway through deserted as the AP-36, does not seem far-fetched order 150 km/h of cruise speed, if all the security systems are much more alert than a human drivers.


that Is to say, in the absence of traffic would be maintained 150 km/h, and the trot would appear to other vehicles. Once you have “free reign” would take up the pace. Already happens with controls cruise assets, as if programmed to 200 km/h, that having cars in front molds to the pace of the others. Except for the more sophisticated systems, do not take into account the legal speed limit.

I understand that the majority of manufacturers they will advocate for the enforcement of rigid rules in stand-alone mode, and if someone wants to drive faster will have to do it in manual mode or semi-autonomous, and always under his strict responsibility.

The technology allows the authorities to ensure that the compliance is more pure: radars, cameras overtaking or the use of safety belts, devices, the future exchange of data between vehicles (V2V) or infrastructure (V2X)…

In the future we will have this kind of debates: you can choose not to comply with the rules?
