Economic analyzes on the passage from 90 km / h to 80 km / h in France ...

[Gaston]

These are special cases and the GPS is still very accurate and it improves all the time.
I will have to specify enslaved the maximum speed.
Nothing will stop the police from putting their portable radar.

I was thinking rather of the opposite case where the system will suddenly slow down the car traveling on the highway because it believes it has taken the exit.
It may surprise the following cars.

[Gaston]

This would result (at least for new cars) in the passenger compartment (but perhaps it already exists) if the safety distance is exceeded as a function of speed.

It exists on most models that are equipped with the emergency braking system (or anti-collision radar).

In general, an indicator (orange) indicates that a vehicle / obstacle is too close taking into account the speed difference, this allows the driver to make a decision (slow down, double?) Before the automatic braking activates.

These cases can be solved by software if you start from the premise that the driver is responsible and not stupid. I can not go into details because inevitably it would bring other questions.
Anyway, this is just a concept which from my point of view is technically viable for a low price.

If we start from this premise, no need to put on-board boxes, just signs on the side of the road for the driver to respect them

I'm not very keen on recent cars

I try to stop before the appearance of computers

But on this point all the better if it exists even if it should be innate for 99% of drivers ....

Which is far from the case ... as if sticking saves time

[Adrien (ex-nico239)]

Hmm, you're still scary ...
Do not give bad ideas to politicians who dared not go that far!
Unfortunately, speed limits only annoy those who respect them.

Who spoke of a fine?

Just make think of the truffles that sticking is used for NOTHING

No, limitations also annoy those who follow those who respect them and who cannot exceed them (because of the traffic in the opposite direction or the configuration of the road ...)

Un interesting article on social accidents and the current treatment of road safety in "disembodied" mode.

An interesting article on social accidentology and the current treatment of road safety in "disembodied" mode.

this article, as interesting as it may be, falls into an excessively focused analysis on the social part of accidents. The big cars only offer additional physical security at low speeds (that's always good, of course), but two vehicles using 80 or 90, each one, does not change the final result: dead people on each side. . In addition, the less favored social classes increase the number of drivers on the roads, without modification of these, provided for a smaller number, with trucks in a row, invisible signs or despite common sense and that doesn’t is not dependent on social classes either. Let's say that the stewardship does not follow and the radars are only plasters on wooden legs: it helps, but it does not replace a real leg.

[Ahmed]

Precisely, the interest of this article is to show, supporting figures, that there is a significant correspondence between accidents and social class, what the usual analyzes try (very well!) To conceal by a construction of globalizing neutrality.
Moreover, by reading your argument, it seems that you did not read the article in question well ...; thus, it is specified there that far from your example of two vehicles "filling up", the "working" classes mostly killed themselves, by an exit from the road not involving another vehicle ...

[Adrien (ex-nico239)]

I'm afraid we can make this observation in many other aspects of life ...

I do not know if this exists elsewhere: a comparison of the life expectancy of the "poor" compared to that of the "rich"?
