Am I doing this right?

Yeah, but the youth vote doesn't usually matter that much because, you know, young people are too apathetic and don't come out to vote.

Also, what problem? It's pretty consistent with what we know about how people vote. And it's also entirely correct to say that younger people have a lot more at stake when it comes to this whole Brexit thing, whatever the consequences may be

It's not exactly wrong...

It would be really hilarious for Britain to end up losing Scotland to the EU

FYI: I seriously didn't care about Brexit or not, but all the butthurt from both sides is hilarious.
 
I'm here for the laughs and dank memes.

It took a bunch of wars, but finally France has won versus the UK.

I just want to see the hilarious AH.com posts that will result from this.

Also, they're most likely going to lose their S&P AAA-status.

But I SERIOUSLY hope Scotland will get another referendum.
 
Also, apparently younger people voted to stay, while older people voted to leave.

Good job, Nigel.
 
"If we leave, we can save 350 million pound a week!!"
 
*leave*
 
"Eh maybe I lied"

Holy shitballs. That ship just... exploded due to overpressure inside the hull?

Some pictures I was able to find.

I'd willingly pay for an offline version of WOT. Just for the sanity saving effect of not having to deal with the swarms of bro-tards.
 
As it is, I'm not playing at all.

Check out this interview on my site with author Robert Forczyk.  We talk about his latest book "Tank Warfare on the Eastern Front 1943-45" as well as his career as a US Armor officer.

So something that's been bugging me about WoT recently, is that they've stopped putting tanks for sale in the tech tree. Something like 80%-90% of the premium tanks they've put out in the last year are only available to buy in bundles. If someone buys gold and wants the tank, well fuck them, if someone earns the gold and wants the tank, fuck them. Only option left to be able to catch 'em all is to spend $40 on whatever shitty premium tank they release for the month.

I'm sure that all the SH regulars will know this backwards and forwards, so this is more for the benefit of newer people, or people who stumble in via google, or people who want a quick link they can throw out as an answer to anyone who asks the question.
 
So, what's with the goofy-ass road wheel design on German WWII AFVs?

You may have run into a variety of explanations for this running gear design; that it provided a smoother ride, that the design saved rubber, or possibly some other rubbish.  Like the myth that frontal drive sprockets provide more traction (seriously, how in the hell is that supposed to make any sense?), these wrong explanations of the merits of interleaved road wheels seem to rise from some quote taken out of context.
 
The interleaved road wheel running gear may have saved some rubber relative to an alternative design that was particularly wasteful of it.  But interleaved road wheels are not particularly economic in this respect because, and I realize this is a complicated concept to explain so I'll try my best, they have more wheels.  Interleaved road wheels do allow for large wheel diameters, and a larger diameter wheel will spread wear out over a larger circumference.  So interleaved road wheels might allow for the rubber on the wheels to last longer, although their construction would require more in the first place.
 
Interleaved road wheels would not improve ride quality either.  The ride quality of a tank is not a function of the size or number of wheels it possesses, but of how they are sprung.  So, it is possible that in certain competitive trials an interleaved road wheel design outperformed a design that lacked this feature.  I could readily believe, for instance, that the tiger (H) had a better ride quality on rough terrain than the tiger (P), or that the SDKFZ. 251 had a smoother ride than the M3.  However, this would be because the tiger (H) and SDKFZ. 251 have independently sprung road wheels on torsion bars while the tiger (P) and M3 do not.

So, what do interleaved road wheels do?
 
They have two principal effects; one is a small benefit, and the other is an enormous detriment.
 
The small benefit of interleaved road wheels is that they spread the weight of the vehicle out more evenly on the track links:
 

 
The weight of a tank is not completely evenly spread out on the contact area of its tracks.  This is because tracks are not rigid.  If they were, they would be mainly ornamental and tanks' engines would just be for show.  More of the weight of a tank is concentrated under the parts of the track that the road wheels are sitting directly on top of.  Additionally, once a tank starts to sink into the soil a bit, larger road wheels work better than smaller ones because the larger ones have more contact area.  But you can only fit so many large diameter road wheels in the space of a tank's hull.
 

Dynamic!
 
 
So, the only way to have lots of road wheels and have big road wheels at the same time is to interleave them.  Simple as that.
 
If you would like an exhaustive look at the development of the semi-empirical MMP equation, read this.
 
The major, crippling downside to interleaved road wheels is that it makes changing the road wheels extremely time consuming.

Lucas Friedli reprints in his book on big cat maintenance a report from a training unit complaining that replacing the inner road wheels of a tiger tank took ten hours.  That is completely outrageous, and was a contributor to the poor operational availability of the big cats.
 
For this reason, interleaved road wheels have rarely been used after World War Two; only on a few French prototypes and a Swedish APC:
