Should cars have built-in speed limits? Some think it’s time

In a straight comparison yes. But they dont consider the fact that one uses fuel for a longer period of time.

CO2 is co2…. A gallon of gas has a set amount of co2 released when burned.

Why govern the car ...... Take a smarter approach from the land that invented the super highway . The Autobahn has a variable speed limit, ... traffic conditions, weather, , accidents..... It's all constantly being scanned... over head signs warn drivers of problems & adjust speed limits to safety adjust for changes.

gee , ya think

Yep.  If you slow down to say 55 the vehicle will emit less co2 then a vehicle at 80 cause it is burning less gas per mile.  They put speed limiters in cars they can control emissions in greater and desired amounts.  Easier to do then go all EV transportation in the near term.

Of course it will emit less. But to travel the same distance it will emit less for a longer time.

Emitting less over a distance is well emitting less pollution!  Glad we agree.  What does having to emit less for longer relevant?  Less c02 per mile is less co2 emitted per mile 😂

You dont know it is emitting less per mile. You only know it is emitting less per minute.

Otherwise you would have run the math and proved it ny now.

A gallon of gas has 19.42 produced when burned.  It’s on the epa window sticker and tells you how much the vehicle emits per mile.  A 40 mpg vehicle will emit half the co2 per mile then a vehicle that gets 20 mpg.  Just fact that there is an exact known quantity of co2 emitted from a gallon of gas when burned.

OK, we all knew that. You still have not proved your claim.

Are you going to sit here all night and not prove your fact?

You slow down say to 55 a vehicle will get better mpg then at 80 therefore with the better mpg of speed limit the less fuel burned which equals less co2?

not very bright are ya? 
 

simple question will a vehicle burn less fuel at 55 vs 80 mph to cover a mile distance?

I dont know, I am actualy still waiting for you to prove it will as that is your claim 

A vehicle running at 40 mph will burn a certtain amount of fuel to go 40 miles and will take 1 hr to do it. Obviously burning fuel the entire time.

A VEHICLE GOING 80 MPH WILL OBVIOUSLY BURN MORE FUEL PER MINUTE , BUT WILL BE BURING FUEL FOR ONLY HALF THE AMMOUNT OF TIME AS THE ONE TRAVLING 40 MPH.

there is nothing to prove in common sense.  If you limit vehicle speed to 55-60 it will produce less co2 on the highway

https://www.energy.gov/eere/vehicles/fact-982-june-19-2017-slow-down-save-fuel-fuel-economy-decreases-about-14-when
 

19.42 lbs of co2 per gallon is produced no matter if it’s burned in a Prius or ram Hemi.  One just goes farther on a gallon emitting less co2 per mile.

it’s right on the vehicles window stickers dumb dumb.  It’s required by law that it be on the window sticker

And again , you still refuse to admit the obvious. The one going faster and obviously burning more will do so for a shorter period of time. 

It dosnt say that on the window. Someone with the ability to think has to actualy think about it. Something you apparently have no desire to do.

Yep and it emits more pollution per mile then the slower vehicle cause it burns more fuel to cover the distance

 

The window stickers these days have co2 per mile on the combined cycle.  It law since like 2013 you retard

are you really this obtuse?

And the slower vehicle will be burning that amount of fuel for a longer period of time. 

 

a 2017 ford f150 with a 2.7 running empty will run at 80 mph in 10th gear at 1900 rpm.

Same truck running 40 mph will run in 7th or 8th gear running about 1650 -1700 rpm. 

Obviously it will burn more fuel at 1900 rpm then at 1650 rpm. But it will burn more fuel for only 1/2 as much time as the it would be burning fuel to travel the same distance.

Vehicle going 55-60 vs 80 mph…. Fuel economy difference?

Of course.

Vehicle going 55-60 vs 80, Travel time for same distance differance?

Travel time longer the slower you go but less fuel you burn to cover the same distance while at slower speeds.  Mpg gallon better at 60 then 80 mph?

Yes it is better at 60 then 80, but will burn fuel ( even at a better milage) for a longer period of time then the vehicle traveling at 80.

15 mpg (80 mph) vs 20 mpg (60 mph)…. Go 60 miles what did each burn in fuel to cover that distance?

Oh come on , be realistic , What kind of faggot wants to drive 60 mph?

Non answer…. What does each burn in that scenario in gas?  And you can calculate how much co2 was emitted for each

You also dont know what each vehicle was getting for milage . Does your lovely window sticker say what the vehicle gets at 80 mph?

One burned 4 , one burned 3 . So you are really going to waste your time to save $3 ? 

The one that burned 4 created 77.68 lbs of co2.  The one that burned 3 gallons created 58.26 lbs of co2.  Now you know why they may limit vehicle ice vehicle speed.  Easy reduction attainable in ghg emissions.
