Also imagine a ruler straight road for 20 miles that you can see the end of, and you're the only car on it for most of the 20 miles.

There's an exquisite scene in 'The World's Fastest Indian,' where Burt Munro has a roadside chat with a Highway Patrol officer, after a 165-mph,lead-brick sprint west of Wendover.No citation,just a neighborly safety comment.

Phil Knox is going to like this.

Thanks John!.I did go by Mojave Airport to see it after DARKO/Bonneville,but it was past office hours and they were already locked up for the day.It would have been interesting to visit with them.I also wanted to see Scaled Composites' 35-foot,5-axis,CAD-CAM, foam billet,milling setup (press a button and get a fuselage).

Sorry! I didn't say. I was born and raised there,and moved to Texas in 1975,after leaving the US Air Force.And yes,the (Nixon) 55-MPH National Speed Limit was still in force.
And a 'Small-World' trivia moment: Fembot-L was married to Ph.D. candidate,Patrick Sutherland,of The University of Texas at Arlington,Department of Mathematics,who was tasked with,and a position created specifically for the nationwide,uniform data acquisition,and stochastic statistical analysis which led to the adoption of the 55-MPH speed, as the 'sweet-spot' for energy efficiency and highway safety.

I always thought 55 was the standard because they knew people would want to do a mile a minute to keep the math easy, and they wanted to keep everyone on edge.

Because you won't know you're saving gas unless you have your face rubbed in it.

Looks like a lot of thought went into the decision.For the 20-years it was in force I observed very low compliance and very low enforcement.Imagine FDR's 35-MPH National Speed Limit for the duration of WW-II.

the 55 limit is based upon old outdated information.

that might apply to a 2/3 speed automatic and 3/4 speed manual transmission only...

with newer vehicles occupying 99% of the vehicles on the road today and a 6 to 12 speed automatic transmissions & CVT this 55mph deal does not apply..



the current system is setup for revenue generation $$$$$$ how much money the state or city can steal from you
basically FOR PROFIT
and not safety or energy efficiency... but they will always claim it is for the ladder.. if I go 55MPH fixed speed my fuel mileage is 21-23MPG on the same route using a variable speed upto 90mph I can get 31.5 MPG...
and upto 90 in on a downhill, to get up a hill that is coming up this saves a ton a fuel.. on the return trip that is where the huge loss is at.


That is being HIGH efficiency.. NOT driving erratically or rapid lane changes.. i only drive based on road conditions most of the time normally the freeway is packed and only going 20mph or so haha so it's just rolling in autostop


fun fact most crashes happen at lower speeds.... you more likely to have an accident in the city streets then on the freeway.. (city streets include highways that don't have a concrete center divider )...

and on the freeway it's more likely to happen in bumper to bumper traffic at 5-10mph

55-mph was just a compromise.It wasn't as onerous as FDR's 35-mph national speed limit during WW-II ,however the physics demonstrated measurable savings to a nation being manipulated by foreign powers,until they could make a plan.All you have to do is look at the aerodynamic drag force and power equations to see the savings.
The safety aspects are borne out also from the physics,generated at Texas A&M University and used nationwide.Also a cube function of velocity.
A 55-mph speed limit today would affect physics identically,it's just that the average mean passenger car is different aerodynamically and rolling resistance wise,as in 1974.Engine BSFC and power-train efficiency has been improved.
My 16.64-mpg at 80-mph pickup will get 36.92 mpg @ 55-mph.It's a simple concept and perfectly germane to national energy strategy,or lack thereof.

We have a national energy strategy. It's to make money off of the consumption.

[freebeard]

No.

Funding for President Donald Trump’s plan to fill up the nation’s emergency oil reserve to help struggling drillers cope with the price crash failed to make it into the latest stimulus legislation but could return in other forms.

Lawmakers eager to get the stimulus package to the president essentially opted to defer a fight over whether to pair the oil purchase with funding for clean energy. But the issue could arise as Congress takes up additional coronavirus-related legislation in coming weeks.

In a letter to caucus members, Senate Democratic Leader Chuck Schumer claimed victory after blocking a “bailout for big oil.” A previous Republican draft of the bill contained $3 billion to top up the Strategic Petroleum Reserve.
