Following the introduction of a mph speed cap on all new Volvos last year, Renault has now announced it will follow suit. Engine power will then be limited to match this, preventing the car from exceeding the speed limit. It will be possible to override the system for the current journey by pushing hard on the throttle, however the system will be engaged every time a car is started.
If you think you can simply keep pressing a little harder on the throttle to break through the system, think again. A feature already seen on all new Volvos and models such as the Ford Focus , the speed limiters will come alongside data loggers, autonomous emergency braking systems, lane keep assist, driver fatigue detection systems and other safety measures. If so, how will the car sense this? These problems are being addressed by developers of AVs, for example by having sensors to detect the proximity of vehicles behind, as well as in front, of the car.
Then there is the issue of ethics, or moral responsibility. This might be seen as a responsibility gap. Fifth, the Law Commission, the organisation that reviews laws in England and Wales, is running a study into the law related to AVs.
The study questions whether or not AVs should be allowed to break the speed limit. My view is that all the manoeuvres the car plans to undertake should be defined to stay within limits, but an AV should be allowed to exceed the limit, where this minimises the risk, such as completing an overtaking manoeuvre where road conditions have changed unpredictably since starting to overtake.
Drivers will have discretion over this — but we would still need to know how drivers would respond to the technology. Analysis of data from flight recorders in the aerospace industry has been a major factor in improving flight safety. But a key point here is defining what is recorded. Consider the SoS problem — what do we need to know about other systems in the car and would we need data from the black boxes in other vehicles to get a full understanding of an accident?
Nonetheless, black boxes in cars could be a much greater contribution to road safety in the long run than speed limiters, especially as we move towards AVs. The more fuel that is delivered to the engine, the faster your vehicle with travels. A car speed limiter device works by regulating the amount of fuel that is delivered to the engine. By carefully calculating how much fuel is required to exceed a certain speed, the device can prevent excess fuel from reaching the engine.
Typically, a speed limiter prevents drivers from exceeding 73 miles per hour, although the limit can be adjusted to meet your individual needs. Most modern vehicles have a built-in speed limiter, but they are strictly intended to keep the vehicle from reaching incredibly excessive speeds.
Aftermarket speed limiters such as Highway Guardian and Family Link are used to limit the speed to a safe pace. While a built-in limiter may prevent you from traveling more than miles per hour, an aftermarket one is intended to regulate you at a much slower pace.
This is why it is ideal for teen drivers. You should also take into consideration that in rare instances, it is actually safer for drivers to momentarily exceed the speed limit to overtake other vehicles that are traveling too slowly. However, it is far more likely that speeding will cause accidents rather than prevent them, so a speed limiter is a wonderful idea for teen drivers. The cost of speed limiters varies depending on which one you choose to install. The amount of activity that the device measures also plays a role in how much it costs.
For instance, Family Link, the technology created by General Motors and Ford, will soon become an available feature in standard vehicles, so you can upgrade without paying for the device separately. The difference is the Highway Guardian primarily monitors speed, while Family Link records all types of driving behavior. Because it is a more comprehensive device, you will pay more for Family Link as a feature in a GM or Ford vehicle.
Highway Guardian, however, is a one-time purchase and can be installed on any brand of car, not just GM or Ford. If you want to have a comprehensive understanding of how your teen is driving and where he or she is at all times, it may be worth it to pay more for a new vehicle with Family Link.
Although most vehicles come with a built-in speed limiter, you will need to remove it if you want to replace it with an aftermarket device that further reduces speed. Because installation involves reconfiguring several wires and the computer system on the car, it is best done by a licensed professional.
First, the technician will remove the original speed limiter by disconnecting the wires and taking apart the fuel injector system. Next, the new speed limiter is set in place. If everything goes smoothly, the process typically only takes an hour to perform.
