Looking for transport of the future

Transport and new transport: energy, pollution, engine innovations, concept car, hybrid vehicles, prototypes, pollution control, emission standards, tax. not individual transport modes: transport, organization, carsharing or carpooling. Transport without or with less oil.

Overall, a few tens of thousands because there are unfortunately not only road accidents!

But being a drug, it's not just lobbies. For other products, traffickers do very well on their own to cause as much havoc: cocaine, cannabis, etc.

The problem with drugs is addiction. Before the state! I admit that with alcohol, the weight of lobbies is added and further complicates things. As added the difficulty related to the fact that socially, it remains valued / rewarding!

We do not live in the country of bisounours!

You just wake up ? you know where we don't live? lol

You will save a lot more life by ringing the cars at 130 km / h and by making the laws as it should be for all, than by going from 0,5 to 0 of blood alcohol level, that's for sure!

Did67: Indeed in the automobile there is much better to do, and one cannot say that the drug is not there for much in the road accidents. In the 73's, during the highest mortality peaks, the drug was not very present and it was there that there were the most accidents. Of all the accidents to date, how many are due to drugs? maybe not even 0,4% or 0,7% and everyone else hadn't. The 99,5% of the problem is not that ... it's not useless to talk about it.

It all depends on who we listen to! According to the defenders of the speed reduction this would be the cause of multiple accidents, according to the defenders of the motorists, it would be only minimal in the fatal accidents and each advances credible figures.
Then, you have to differentiate between accidents on the highway and those on the road, cars and motorcycles, etc.
For the BAC it is necessary to compare the countries with or without with equivalent parameters elsewhere, which is not easy. But, according to the authorities, having reduced the dose seems to have been considered to have a measurable impact. It is likely that this rate will be further reduced in the coming decades.
The authorized blood alcohol level while driving differs greatly between Member States. While in most EU countries the authorized level is 0,5 mg / ml, in others it varies between 0,2 mg / ml and 0,8 mg / ml.
Some countries, such as the Czech Republic, Hungary, Slovakia, Romania, Estonia and Latvia, do not authorize any presence of alcohol in the blood while driving.
The European Commission has recommended the adoption by all countries of a normal authorized rate not exceeding 0,5 mg / ml. This harmonization seems to be taking place gradually since countries like Ireland or Cyprus have reduced since their authorized rate to 0,5 mg / ml

It is still necessary to distinguish legal drugs from illegal drugs, alcohol being a legal drug, it should not be forgotten, when when people talk about drugs they think of cannabis, marijuana, etc. Medicines are also drugs, still legal, but drugs all the same! Hence the difficulty of wanting to legislate on illegal drugs and to regard the legal as negligible when these are the ones that affect the most people (France is world champion in the consumption of psychotropic drugs) and sleeping pills.
FRANCE GOLD MEDAL FOR HAPPINESS PILLS
-------------------------------------------------- -----------------------------
THE NEW OBSERVER - September 5-11, 1996, Fabien GRUHIER
8 million boxes of tranquilizers consumed each year

Are we the most depressed people on earth? No. However, a book-report by Professor Zarifian establishes irrefutably that our country consumes from two to four times more anxiolytics, hypnotics, antidepressants and other neuroleptics than any other European country. Here's why.
(…) There remains a sad truth. We have known it for a long time, we keep saying it, repeating it, writing it and reading it everywhere: France is the world champion in all categories for the consumption of psychotropic drugs, these famous little happiness pills - tranquilizers, hypnotics, antidepressants and other neuroleptics

Janic: you want to compare the other countries you don't even know how they work (mortality) you look at the neighbors to find out what is best to do? there is not enough in front of your eyes ?? do you have to go look elsewhere? you listen to everyone because you have no opinion on the question and you wait for them to give you a ready-made answer? has the EU recommended having cars that do not exceed the maximum speed limit? No and why? you looking for the question? let's compare the comparable. Because, according to them, cars that can go at 200-300 km / h and exceed speeds are less dangerous than someone with 0,2 in their blood. This is not my opinion.

There is no need to go to Brasserie or Hungary to know the mortality and know what is happening here and know what there is to do, I do not share your comparison method !! Letonia, Hungary do what they want, I don't spend my holidays or live there, and it's not me who will tell them what to do and what to change.

Muslims do not allow drunk driving but they still have cars going 200kmh, and if they prefer to die going 200kmh rather than drinking 0,2% it is their problem not mine. It is easier to ban the sale of cars that go 200 km rather than the sale of alcohol which is much more difficult to prohibit sale.

In number of deaths / car.km the roads limited to 90 (departmental ...) are much more dangerous than the highways, and the accidents are not mainly caused by excessive speeding compared to the limitation! .. .

Alcohol is the leading cause of accidents in France, in particular among young people: almost one in four young people (1%) killed on the road in 39,8 was killed in an accident with alcohol.

Yes it's right.
Little reminder:
Speed ​​is an aggravating factor on two main points:
1) The power believes in the square of the speed:
Recall that if the speed increases, the kinetic energy increases squared of this one either: Ec = ½ m × v2

By doubling the speed, the impact power increases by 4, therefore past a certain threshold, and those despite passive or active safety technologies, the laws of physics greatly reduce the chances of survival of the passengers.


2) Braking distances: direct consequence of point n ° 1, if the speed increases, the distance traveled per second increases in proportion to this, so the faster you drive and the more time it takes to stop; where the need to respect the safety distances to the letter.

To these there must be added the state of the driver: reflexes related to fatigue, alcohol, drugs, the degree of nervousness, age, sex etc ...

Now, speed alone does not explain all the problems, because it is often a question of multi-factorial accidents. (See above + weather conditions, traffic conditions etc ...)
For example, it is less dangerous to drive on a motorway at 130 km / h on a Sunday morning than to drive at 80 km / h on a Friday evening on a so-called "fluid" ring road.
But in any case, the speed don't fix anything, hence the efforts to reduce it for years ...

On the motorway, three quarters of the journeys are on straight or almost straight lines allowing a clear vision favoring anticipation, this is not always the case on national roads, which tend to follow the landscape more.
In addition, the highways are closed (except the ramps) and fenced around the forests, which is not yet the case for RNs.
Overall, the highways are equipped with better infrastructure and more information ...


On the other hand, if we reduce the speed AND the number of vehicles, and sprinkle the whole with a program of prevention, deterrence and road repression as well as technologies that go well with it, we would arrive at a fairly good result. satisfactory.

German documentary, centered on Hyperloop, where teams of engineers of several nationalities compete in a competition of models of the futuristic transport of Elon Musk. The German team wins, of course ...

Almost irrelevant, except in the conclusion where we suggest improving the efficiency of current transport, the only good idea in this documentary!
