The speedometer is an essential element in a car, many models have dual display, digital and analog
Until the mid of the 70-80s, the cars that were circulating in Spain -and a good part of the world – not normally had a top speed much higher than the legal one. It was following the oil crisis when Spain adopted a speed limit of 100 km/h, and in the early 80’s was set at 120 km/h for reasons of energy and security.
Currently, the maximum limit in Spain is 130 km/h, but it does not apply
nowadays cars often have tips well above what the driver’s going to achieve in the day-to-day. The compact and utilitarian than 100 HP of around 180-200 km/h. Above these figures, in Spain a crime is committed. In other words, plenty of top-end speed in the car today, except at sites very timely as the Autobahnen German.
First came the countermeasure of the limiter, a volunteer speed, which prevents the driver to exceed unwittingly a programmed rate, or a detector that do the same but do not cut the acceleration. These systems are always voluntary, and the driver decides to. The vast majority of cars, except in models very exclusive, does not exceed 250 km/h limited to electronics.
The cars of Tesla are becoming more correct in respecting the traffic regulations, even if their owners want to hurt them knowingly
As you approach the age of driving, autonomous, the manufacturers are programming the cars to meet the rules of road, that is to say, they will cycle up to the limits imposed by the signals. If we consider as constant the density of the traffic, this will cause half the people to circulate a bit more slowly.
In the first versions of the Autopilot Tesla drivers could schedule a speed above the legal limit. In a subsequent review was allowed to exceed the limit in 5 miles/hour (almost 8 km/h), and in the last update that can only be done on dual carriageways. On other roads the cars will respect the maximum limits.
There are those who think that can be bad for road safety that you can not travel faster if the driver wants to do. Technically you can still do just that manual control. Although the manufacturer does not answer for what they do on their cars in automatic mode -the responsible is the driver – it is not a bad idea that the cars comply with the standards. For that you got, right?
The first detectors or speed limiters may not know the limitation, it is the conductor who brings it to your discretion
Imagine this situation. A car autonomous or semi-autonomous sets to meet the limit of a road in an environment where human drivers tend not to respect it. If that car passes a zone boundary x one lower, you will have to slow down, even using the brakes. That can be a point of conflict, abiding by the rules versus those who do not.
studies on speed feel that is more dangerous than many vehicles with different speeds. In a scenario in which the speed is homogeneous, there is greater security. The speed, in itself, is harmless. Only implies a problem in combination with something else, as a distraction, an exit path or a collision.
We have another example in the limiter intelligent speed Ford, that when it captures traffic signs that inform you of a limitation than you are driving, the car loses speed to comply with the signal. In this way you can avoid penalties for not respecting a limitation that has not been seen or not to be respected in manual mode.
With the technology of recognition of traffic signs (TSR) the cars may know what is the limitation that you must meet
The speed limits are a convention rules, thinking about users is very different for each pathway. Your compliance is going to improve, on the one hand by the repressive measures -radar and speed controls section – and on the other because the cars that lead to autonomous and semi-autonomous, they are going to respect them.
sometimes it seems that we forget that, if all road users complied with the rules, the movement would be much more secure. Imagine what would happen if no one travelled without a belt or without a helmet, if no one skipped a STOP, if you respect the speed limits, turn signals, priority pass, etc, it Sounds like less freedom, but collectively, we’re going to win.
ever more, the maximum speed of a car will be a fact more comparative than practical. Even in more of a circuit can be a data irrelevant if there is not enough straight to reach it. There was a time in which the cars ran more than necessary and only depended on the driver that this was not so. That time is the present, and is beginning to decline.
