as for sports cars, they're a waste of gas true. but nowhere near as lethal as an SUV since they don't have 250% momentum "quad damage" bonus. plus the middle-aged balding semi-impotent man behind the wheel of a sports car is more responsible since he is going thru is mid-life crisis but necessarily wanting to end it. while SUVs are driven by egocentric inexperienced youngs that think they're invincible.
1) so they waste gas
complete bull.
take your sports car, lets use the mustang (see, im not GM biased!) it weighs 3450 lbs or 1547 Kg.
your typical SUV, lets use the Tahoe. it weighs 6500 lbs gvw 2wd or 2948 kg.
now, take your comfortable cruising speed in both. tahoe, i would say you are comfortable around 70 mph or 31.29 m/s (meters)
for the mustang, i would say you could comforably cruise at 90mph or 40.23 m/s
now, 31.29m/s * 2948kg = 92242N
and 40.23m/s * 1547kg = 62235N <--- thats a HELL of a lot of force, anyway you look at it. and yes, that is assuming 90-0 in 0sec. flat.
250% momentum damage? more around 67% more force.
so, because SUV's are made higher, they make themselves unsafe? hmm, why dont cars go higher, then it would be equal. think of it both ways.
middle aged, balding men drive sports cars, true, young teens drive mustangs, because they are cheap. middle-aged balding men also drive SUV's, my father drives one, most of my uncles drive them. you cant say young ppl only drive them.
and rollovers, ok, so certain suv's have a high center of gravity.

What kind of weird way is that of calculating force? kg x (m/s) != N[/quote]
damnit, i just noticed that.
lets put m/s as m/s^2 giving you a deceleration speed of 1 second, and you still get the same force.

Nonetheless, your results are based on bullshit data. I'd have to say that the average speed a mustang is driven isn't that much different from the average speed that a Tahoe is driven. Where you get the idea that the mustang is going to be going 90mph is beyond me. Unless mustang drivers get a couple of speeding tickets a day. (or you travel exclusively on some interstates and turnpikes) Plus, it's obvious, since you're calling it a "deceleration speed", and a deceleration speed measured in seconds at that, that you're really not good enough in physics to be attempting to use it to prove your point.
If a Tahoe has a head on collision with a regular car with far less mass, each going identical speeds, because of conservation of momentum, the Tahoe will not slow down as much as the car, the car will actually be knocked backwards - the magnitude of the change in momentum of the car will be GREATER than the momentum it had before the collision. Thus, driving a typical car head on into a Tahoe, each going 65 mph, will, for the car, have about the same effects and running into a brick wall at 90 mph (or more). (of course, a brick wall that begins a little higher off the ground)
Add on to this that a majority of accidents happen at city speeds, not highway speeds. Personally, in the instance of getting t-boned by another vehicle, I'd much rather have the kinetic energy of the colliding vehicle dissipated by the change in velocity of my car when the frame takes the brunt of the hit, rather than the energy being dissipated by the deformation of metal (the door) into my torso - ouch. It's really hard to compare apples and oranges, (and all the other fruits, since every make/model is different), but if you simply look at the rates, you'll see that SUV's are far more dangerous other cars. It's not a matter of 100 people were killed by SUV's and 25 were killed by sports cars - that's because there are more SUV's... (I'm making this data up, obviously), it's more "50% of accidents between a car and SUV resulted in serious injury to the car driver" vs. "25% of accidents between a car and sports car resulted in serious injury to the car driver." (again, more made up data, but the data is correct in that the percentage of serious injuries is higher for SUV's to cars.)
The gas issue is really because there are too many idiots in the U.S. who just want to join a cause, even if they really don't understand all the issues of the cause (although they usually think they do.) Which is why if you find a rally of these "irrational pig fvckers" as Mill so eloquently put it, you can convince 80% or more of them to sign a petition to ban dihydrogen monoxide (water) - "did you know that dihydrogen monoxide is a major constituent of acid rain?! Let's ban industrial use of this harmful chemical that also contributes to soil erosion." All in all though, decreasing the demand for gasoline (should) cause the prices to fall (excepting that OPEC will attempt to keep them higher) resulting in decreased costs for producing and distributing most goods in the U.S.
edit: I'm just answering the original question: why are SUV's the only vehicles that get ripped on for gas guzzling? Also, sorry for bumping such an old (but bumped prior to me) thread - the option of showing newest threads first, rather than most recently replied threads has disappeared in the new incarnation of fusetalk.
