Safety: will there also be limits on acceleration?

Safety

Some car manufacturers, such as Renault and Volvo, have decided to limit the speed of their cars in order to ensure greater safety, active and passive, and potentially also reduce CO2 emissions, higher at high speeds. The most mischievous have suggested that the speed limit was also established to ensure greater future electric mileage, without therefore having to introduce too many innovations capable of upsetting the motorist's thinking. In this regard, some states have reshaped speed limits, such as the United Kingdom which has decided to reduce some limits from the previous 70 km / h to the current 60 km / h. Even Spain, more recently, has changed the urban speed limits by moving the threshold to 30 km / h.

In addition to the modification of the maximum speed, there are other aspects to consider? The answer is yes and, as an alternative to maximum speed, manufacturers and enthusiasts will certainly return to the best alternative available: acceleration. While on the one hand we no longer find the maximum speed as a value to use for promotional purposes, acceleration is back in vogue and a clear example is provided by Tesla with its new Roadster.

For those who do not. knew, the Roadster will most likely be the fastest car ever. According to preliminary information, the future electric two-seater will be able to reach 100 km / h in 1.1 seconds, thus beating even the Formula 1 that we see darting on television. To put it into perspective, a modern Formula 1 single-seater stops the clock at 1.7 seconds, while a Bugatti Chiron takes just over 2 seconds.

Federicovecchio.com We realize that we are talking about exclusive cars that we will not see frequently on the street, but what happens to the other electric cars? The proliferation of electric vehicles such as those of Tesla or the electric ones of other brands, has brought to the market a series of cars capable of reaching 100 or 70 km / h within a few seconds. We ourselves, in some tests, were surprised by the instant torque available and the ease of access to this type of performance; a Fiat 500e needs just 3.2 seconds to reach 50 km / h, we are talking about a decidedly more accessible electric small car.

If you need a lot of space to push a car to top speed disposition and a clear and precise intent (a sort of premeditation?), for a brief acceleration instead just a few moments on modern electric. How long does it take for a driver to miss a stop or lose their seat in a queue? Very little. One study found that a driver's response to unexpected but common signals, such as a car's brake lights, is about 1.25 seconds. Surprise events, such as an object suddenly moving on the road, take about 1.5 seconds.

Having a car that can reach 50 km / h in two or three seconds can be definitely dangerous; naturally we are referring to people who are not very attentive to driving and also to novice drivers who, with the current incorrect kw / ton limits reported on electric cars, could shoot freely without any limitation. The question now arises spontaneously: in how many years will someone ask how to limit acceleration?
