Absolutely, we suck as drivers.....
Somewhat of a "car guy" here. Anywhere on the web: When these threads pop up, you will usually get the self professed aficionados who insist that they can out-drive the ABS, or the electronic stability control, or whatever feature is being discussed...
The cold hard actuarial tested reality is that, as a whole, we cannot, and my sneaking suspicion is that the vast, vast majority of self-professed outlyers can't either.
My other pet-peeve are people who bash side-curtain airbags as "useless crap" that weighs down their car. 1) the systems don't weigh that much 2) go visit a closed-head injury rehab center and tell me side-curtain airbags are useless.
By that logic hybrids in cars wouldn't make any sense either but they do. They are demonstrably more efficient at comparable horsepower even in the face of the conversion losses.
hybrid cars do well because the electric motor and regenerative brakes help them out greatly in city driving..
BUT, you are overgeneralizing: A hybrid setup, be it a series hybrid, or a parallel hybrid is NOT demonstrably more efficient in high endurance constant speed operation..
Energy transfer is not free. A generator that puts out X watts of electric energy has to have X + {some number} of watts of mechanical put into it by an internal combustion engine. And likewise an electric motor that has to supply Y number of watts to a wheel hub has to have itself Y + {some number} of watts of electric energy put into it.
Mechanical transmissions are not lossless either, but modern ones do quite good, especially when they lock into their highest gear and the IC engine driving them stays at a constant RPM in the RPM range where they are most efficient.
A internal combustion engine, chugging along at a constant 1800 RPM into a good modern tranny at high gear is going to do better than if it was running a generator that was charging a battery, that was hooked up to a wire, that ran to a motor, which turns a wheel. This is precisely why the first generation of chevy volts locked in to a purely mechanical mode at highway speeds, it doesn't make sense to hybridize in that use case.
It makes great sense on trains, because you it allows you to get power to wheels on various points on the train, which is highly advantageous and impossibly difficult to accomplish mechanically.
When you scale down to car or truck size, mechanical transmissions work reasonably well, and are very efficient these days. There is a significant loss, compared to a purely mechanical setup, that occurs when you turn mechanical energy into electrical energy in a generator, just to send it over the wire and convert it right back to mechanical energy at the wheel.
If the bulk of the electricity stored in the batteries comes from a cheap source (i.e. an outlet), it still makes sense, but if you are talking about a high endurance application where the vast majority of electricity is generated locally it doesn't.
Somebody needs to tell a certain company that does third party security validation that. MD5 hashes have use in things that have nothing to do with security, and they constantly get flagged.

Revelation 8:10-11English Standard Version (ESV)
10 The third angel blew his trumpet, and a great star fell from heaven, blazing like a torch, and it fell on a third of the rivers and on the springs of water. 11 The name of the star is Wormwood.[a] A third of the waters became wormwood, and many people died from the water, because it had been made bitter.

Most environmentally friendly motor fuel is diesel
no it isn't, not even by a long shot.. Natural Gas and Propane vehicles trounce them in terms of environmental impact. In most places, considering the power grid is rapidly cleaning itself up, electrics would as well.
Do you think that diesel fuel magically jumped from miles down in the earth, refined itself, and showed up in your gas station all by itself? It's a very energy intensive process, using a lot of electricity usually derived from coal or natural gas, and/or coal/natural gas burnt right in the refinery just to get it to that state. So not only is your diesel car a point-source polluter, it is very much a "remote polluter" in its own right..
2) you can bloviate about "remote polluting" electric cars all you want, but the fact of the matter is that coal, as a percentage of the US's energy mix is going down, not up, and its going down quite rapidly. And even if it wasn't (which again, it is), it is arguable that addressing emissions at one managed point-source is preferable to distributing the polution across thousands of engines all in various state of tuns.
The implication that because renewables can't do everything (and currently they can't) means the aren't worth having is just silly..
We should continue, and even accelerate the expansion of solar and wind power... natural gas is ultimately still a carbon source, and far from "clean", but its a HUGE net positive for the environment compared to coal.. inasmuch as it contributes to the displacement of coal plants it is a good thing. It also has the benefit of being highly variable to provide balance to the ebb and flow of renewables.
Today, roughly 90% of civilians who are shot survive. As many as 90% of victims of knife attacks bleed out before they get to the hospital.
This is true. Knives, especially knives over 3 inches long, tend to be more lethal than anything but the largest of bullet calibers or shotguns
No.. this is not true...
Ex EMT here.. Had to deal with the aftermath of numerous knife fights, and knife attacks.. What you have, in the VAST majority of cases, was a bloody mess, but wounds that are survivable, in many cases not even highly emergent. Yes, there were some deaths, but they were rare
With gunshot wounds (be they attempted homicides, suicides, or accidents) the outcomes are flipped. Modern emergency medicine is better than it ever was but you still see many cases where treatment of any kind was utterly futile, many "coin flip" type cases, and a smattering of superficial non-emergencies..
Killing somebody with a knife is a lot harder than the movies make it out to be.. Killing somebody with a 00 Buckshot is ridiculously easy, a 9mm caliber handgun.. harder.. but not that hard..
Also, the contribution of coal, as a percentage of generating capacity, is falling dramatically in the US. Although some of this is renewables (especially in places like Iowa), this is mostly due to the fact we have more natural gas than we know what to do with.
Although this begs the question, is it more efficient to burn natural gas, to spin a turbine, to make electricity, to put into a battery to spin a driveshaft; OR would it be better to just burn the natural gas in an ICE on the vehicle itself? It would seem like you would save a lot of transmission inefficiency by using CNG in an ICE.. But then again, modern combined cycle natural gas generation facilities are highly efficient.
let's be clear hear, when you say "more", that means LOTs more.. going against the Russian war machine on the european continent in 1945 would have been absolutely no joke; they were churning out more war material, including the then world beating IS3 tank at the end of the war, than we were..
Nope, not even remotely similar in plausibility...
1) Russia is actively involved in the current instability in the Ukraine... To deny this is about as rational as denying that the sun rises in the east
2) Russia has, numerous times actually, used natural gas disruptions, or threats of gas disruptions as a political tool
3) America, as you said it, has a massive gas glut. Russia wasn't behaving badly (more or ess) when the big LNG export megaproducts got started off the coast of Louisiana.
Even if Russia wasn't acting pants-on-head crazy and jeopardizing their own self-interests we still would have been able to undercut their price gouging in Europe.. And there is also the Asian market, which stands to be a big customer of North American natural gas, regardless of Russia's antics.
That's as real as realpolitik and real-econmick gets. These are all facts, verifiable from multiple sources.. To say unsourced proclamations that the united states is somehow "staging" political changes in the Ukraine so that we can sell gas is "about as plausible" is pure hysterics...
I don't think it's a coincidence that Russia is acting up, and grabbing what it can grab, right at this moment. Europe's push for renewable energy, coupled with the fact that large-scale LNG exports are due to come online from North America in the next few years means that using energy disruption, or even the threat of it, as a foreign policy weapon is going to be FAR less effective.
