All US cars MPH to be limited to 80 as max speed

If they make cars that only reach 80mph (max), then you're going to have a lot of people flooring their cars. And that's not just to reach 80mph. That also means it's going to ruin your car's acceleration. If 80mph is the speed you reach while flooring the gas pedal, imagine how tough it'll be just to reach 65. The limits in some states are 70 or 75mph. You can't maintain 75mph on a 80mph (max) car for very long without doing harm to your car.
I think you are looking at a very basic means of speed restriction here, probably via a overdamped control system...

take a look at this graph

consider 1 to be the max speed input of the car. the red, blue and green lines are the response time of the car to get to that max speed(for instance).

the red and green line never actually exceed this maximum value and especially the red line finds it particularly difficult to reach this max value.

the blue line however shows a system of control that allows for a overshoot and the system then calms down and oscillates until the dampner takes effect on the maximum value, thus allowing the car to accelerate and perform quick manouvres but over long periods of time, it will then decellarate and stay steady on the maximum value

this also shows how the functions of a car can be controlled without potentially changing the design characteristics of the vehicle' performance.

obviously the oscillatory response is not necessarily an ideal one but a system could easily be designed where a large acceleration output could be employed and then from there, some natural damping decay to a steady max speed.

if you want further illustration, i could draw it on the relevant curve for you.
 
No, this is a terrible idea. Limiting someone to 80 mph is not going to prevent accidents. Most accidents occur at far lower speeds anyways...and are still fully capable of killing people as a result. It's an issue of responsible drivers and proper education/training. If some guy robs a bank and is trying to get away from the cops, he's still going to drive crazy...at 60, 70, or 80 mph.

On that same note, how many times have we seen police chases where they are going well below 100 mph. Just because the police can overtake a vehicle doesn't automatically mean they are going to stop them immediately. They often wait out the suspect until they slow down (due to stop sticks or whatever), or until they are at a safer position to try a P.I.T.

What they need is some sort of EMP Projectile that immediately disables a suspect vehicle.
 
Why don't we just castrate all men to prevent sex crime while we are at it :cmad:
 
No no no. They need to make the speed limit on the roads 80.
 
There are no speed limits in the world that are in the triple digits...why have cars that can reach such numbers?*
 
Actually on the Autobahn in Europe there are sections with no speed limit. You can drive as fast as you want, traffic permitting... most accidents on the Autobahn are fatal.
 
theres a lot of people here saying this is stupid....but why are you saying that? whats your problem with it? because you like to go fast in your car? yeah....thats why the suggestion is a GOOD idea.
 
I am going to speed everywhere for the next week in honor of all you people who support big government ideas like this. :up:

Personally I don't want the government telling me whats too dangerous for me, I'll be the judge of that.

well, see, thats the problem. when you're speeding, you're also a danger to others, not just yourself. so while you're maybe okay putting your life at risk, others are not so comfortable with your putting THEIR life at risk.
 
You could kill someone at 80 MPH. You could kill someone at 60 MPH. You could kill someone at 40 MPH. You could kill someone at 20 MPH.

Let's do away with cars, and instead reinstate horse-drawn carriages; but only under the mandate that the horse not be able to run, as they can go pretty fast.

You could say that about almost any mode of transportation.

very true. but, whenver you get in a car and take to the road, theres a certain level of trust that you obviously have to have in the other drivers on the road. and i have a lot more trust for someone ability to drive safely at 70 mph than i do in their ability to drive safely at 120 mph.

and to everyone who sayd being hit at 100 mph is just as likely to kill you being hit at 70 mph, 2 things:

1. i think if we all had the choice, we'd much rather be hit at 70 than a 100. even if minimal, your chances of surivial/recorvery must be greater.

2. if the person wasnt driving at 100 mph, then maybe they wouldnt be hitting oyu in the first place. driving that fast greatly lessens your ability to control the car safely and appropriately.
 
Cars don't kill people. People kill people. Seriously, most of the people I see who speed, myself included, are actually paying attention to what they are doing when they are driving. As opposed to the lady I just passed who was talking on her cell phone, shifting her manual transition, sipping her coffee, smoking her cigarette, changing her radio station, operating her windshield wiper blades, putting on her mascara, looking through her glove box and reading a paperback book all at the same time while going five miles under the speed limit and swerving back and forth on the damn road. (Yes, I have actually seen a woman doing ALL of those damn things at once)

The really old and the really young can't drive. I see this now. The ones inbetween just do stupid stuff to contribute.

yeah, but even paying attention while speeding, you cant deny that your a safer driver and in more control of the car when going the speed limit.
