Braking distances: the strange calculations of Road Safety to (try to) justify the 80 km / h…
In an attempt to justify the 80 km / h, Road Safety released a study on braking distances … in total contradiction with that published two years ago! #FakeNews ? Really ? Explanations.
The most cinephiles of Site readers may remember this film by Peter Greenaway released in 1988 entitled "Drowning by Numbers, translated in French as" Triple assassination in Suffolk "but which literally means" Drowning by the numbers "…
However, drowning in the figures is what the Road Safety Directorate (DSR, which depends on the Ministry of the Interior) seems to be doing with this new study released at the right time to demonstrate how much it is. necessary to go from 90 to 80 km / h.
Think about it: at 90 km / h, a car would take 70 meters to stop, while this distance would be reduced to 57 m when driving at 80 km / h. That is to say 13 meters of difference which can prove to be very useful to "save lives", according to the time-honored expression. Certainly.
Except that the readers of the Journal moto du Net – whether they are cinephiles or not – remember that in 2016, the same DSR explained – in a very interesting study by UTAC-CERAM about – that the car launched at 90 km / h took … 43 meters to stop !
- MNC of March 30, 2016 :
- Exclusive :
In two years, the total stopping distance of a car would therefore increase by 27 meters ?! There are two things: either Renault has serious R&D problems and its recent models (like the Captur used in the 2018 study) brake significantly less than those of two years ago (like the Clio used in 2016) … Hard to imagine! Either Road Safety has inadvertently tangled its brushes in its calculations, blinded by its desire to do our good, all our good, nothing but our good. Unless … no, nothing.
Braking distance at 90 km / h in 2016: 43 meters
11 meters covered during the reaction time + 32 meters during the braking phase = 43 meters
Braking distance at 90 km / h in 2018: 70 meters…
25 meters covered during the reaction time + 45 meters during the braking phase = 70 meters
Naturally, Site sought to know the explanations of the DSR. On the one hand because it’s part of our job to ask questions and check the information, on the other hand because the interministerial delegate for road safety himself invited us at the beginning of April to the Ministry of the Interior to regret, among other things. , not to be sufficiently questioned by the motorcycle press on 80 km / h…
Since each of our recent attempts has unfortunately not been answered – possibly a spam problem? -, here is the question we asked the services concerned. Answer to follow on MNC (in any case we hope so): stay connected !
