Why do most people speed up when another car is trying to pass???

The force required to overcome air resistance varies with the SQUARE of velocity. Therefore, the faster a vehicle travels, the more important aerodynamics become. This is why a vehicle with twice the torque and horsepower of an otherwise identical one may still only achieve a top speed which is a few mph (or kph) faster.\n\nOvercoming air resistance is paramount to a F1 team. At speed, their vehicle's cross-section (the profile it presents to the wind) and coefficient of friction (how "slippery" the design is) become the limiting factors of velocity.\n\nRace cars must also be designed to provide some amount of downforce, which helps to keep the tires firmly attached to the pavement during acceleration, deceleration, and turning. Finding the winning balance between these factors is a great deal of what separates good teams from the rest of the field.\n\nExcellent question!\n\nEDIT -\nMatthew G ... they say that imitation is the sincerest form of flattery, but one man's imitation is another's plagiarism. Please don't misrepresent my words as your own.

You and fly are in the moving car, so both of you are at rest relative to each other. So when the fly goes from back seat to front or from front to back, it is faster than you, bacause both of you were at rest within the car.\n\nFor example, we all are in the moving earth, so all our speed is relative to earth, we do not take into consideration the earth's speed. I hope I am able to make it clear.

Dear Tony Cologne,\n When you say a red car appearing to move faster, do you mean to the human eye or to the device that the cops use. I think you may have some confusion that is evident in popular lore about the Doppler shift. \nHowever, you might have a point about the cops coming to a complete stop and then catching up again within a quarter mile. At 37 mph a quarter mile is 24 seconds. That means the whole time they are stopping it is adding to your lead as well as the whole time they are accelerating to catch up. Then once they surpass your velocity they have to exceed it enough to catch up within what is left of the 24 seconds they started with. Plus, nobody pulls over right away the instant the lights start flashing. If you had a savvy lawyer you might have a case, plus the judges know these cops usually embellish the truth. Who cares, its a traffic ticket, might as well fight it and have some fun. Its not like you'll get the death penalty if you lose.

People tend to drive very badly every day. They seem to think that a car is meant for eating, putting on make-up, talking on a cellphone, or even reading a book, and not for paying attention to the road and driving. They also think it is ok to go super slow (65 or slower) on the highway, when it actually is really dangerous to everyone around them.

well maybe for some reason your going down a driveway or somewhere where it might pick up speed on its own like a steep hill or anywhere steep and u cant stop it ur gonna need those brakes to help u out or maybe the are there so when the old people wanna race they can hold on to there brakes and peel out lol

Before overtaking the second person you were third. After overtaking, you are now second.\n\nYou're also very, very tired.  :)

That's a rude generalization. People don't use their turn signal less and less as they get old. I've seen people around my age who don't use their turn signals and I'm 18.

Simple enough... they have no respect for other people or for the safety of people on the road. I have been on a multi-lane highway at night with very little traffic. I look in my mirror and there is someone sitting on my bumper with maybe two feet of clearance. I look over my left shoulder... no cars. I look over my right shoulder... no cars. I look at my spedometer... 65 MPH. So it isn't like I am impeding this person from getting somewhere. I just happen to be in his lane when he came up on me. So what did I do? Well, I did what any good driver would do in that situation.\n.\n.\n.\n.\n.\n.\nI let my foot off the gas and slowed down to 35 MPH! He got off my tail real quick at that point.

Is it because everyone else is running faster and they are not keeping up? \n\nThey seem to be playing it pretty conservative... I don't know why... maybe they only have $2 mil to spend instead of $10 mil. \n\nCool color on the cars though. \n\nCheers!

forgot the true answer to that. but heres one. Why do people drive in a parkway and park in a driveway

Because sometimes people are just so inconsiderate and they think thay can handle it. But in fact they can't. I pull over at times but sometimes when i have emergency calls I would jus talk on the phone, but i'll make it quick. I hope people are more considerate because they are not only putting their life in danger, but other people's life also!

yea your right they are c..p ! if they cant be there to hassle drivers they have cameras to do it for them.I just got 60quid fine and 3 points for doing 50mph on the M1 at 1 oclock in the morning !wa...r5

Another way to see it is to consider acceleration versus constant speed. If you're going 60mph your position is increasing at that constant rate, but if you're pushing on the accelerator your speed is going 60,61,62 etc.. so your speed (which is your position vs time rate) is increasing. That is a varying rate. Doesn't have to be strictly increasing though. You could be speeding up then slowing down then back up again. Or maybe accelerating or decelerating faster, then slower. It can be any combination as long as you're not constantly going at one speed.

No and I'll tell you why.  Because when I'm behind someone at a red light, and I'm not paying 100% attention and I see their brake lights go off, I assume they're going, and I almost rear end them.  Therefore as a common courtesy to people behind me who might have spaced out for a second, I don't do that.

Just because a car can go 200 mph doesn't make it one of the better cars on Earth.\n\nIt just means it's fast.

It depends which state you are talking about. That said, and generally speaking, it is illegal to pass another vehicle going the speed limit. It is not illegal to pass a vehicle going under the speed limit as long as you have the right of way. It is also legal to increase your speed to overtake a vehicle as long as it is not an unreasonable speed and that your speed is reduced to the legal limit once the vehicle is passed.\n\nAgain, this depends on the state. In Washington State, RCW 46.61.425 addresses this issue:\n\n"...a person following a vehicle driving less than the legal maximum speed limit and desiring to pass such vehicle may EXCEED (caps mine) the speed limit... at only such a speed and for only such a distance as is necessary to complete the pass with a reasonable margin of safety."
