I'd assume it means that there should be a single chevron between yourself and the car in front?
It's called the 2 chevron rule and you assume there should be 1 chevron between you. confused

At Christmas, if your boss gives you 2 days off, do you assume you have to come back to work after 1 day?

There are a couple of references to this on the internet but no answers that I've found:

How has this tuning company managed to get away with having an almost identical logo to that of Cyprus Airways?

Probably won't matter soon anyway; Cyprus keep reducing the size of their fleet.

It depends on who got it first, and I wouldn't be putting any bets on either side.

What happens to a amputee's blood pressure after they lose a limb?

Does it go up as the heart continues to try and pump blood into a space that isn't there anymore at the same old rate?

or

Does it drop as the body doesn't require blood to be pumped as far?

I hope not or every time someone turns a tap off at home, all the pipes would go bang.

The heart regulates the need for blood, like when you exercise it beats harder and faster, when you relax less heartbeats. It is it's own pressure regulator.

What is the hardest, most complex thing a human can be trained to do? Say in terms of mental information processing / decisions (whether conscious or unconscious) made per second?

Landing a Space Shuttle? Playing a piano concerto? What?

Some of the newer jet fighters must be a struggle, as you've got both feet on the rudders, one hand on the throttle, the other on the stick with your thumb on the hat switch, and I've seen that voice commands are getting into it.
In other words, almost all moveable parts of the body of controlling something, and that's under crazy G forces.

Pulling back into the inside lane after an overtake.

I suspect the newer fighters are actually easier to fly than earlier generations of jet fighters, harder to master perhaps No effective fighter can be all that hard to fly or the pilot wouldn't have any attention left for shooting at people.

If you abbreviate 1 million it becomes 1m, if you to the same with a billion it's 1bn. Why???

Why, when a car is reversing, it makes a higher pitched 'whirring' noise compared to driving forward? scratchchin

reverse gears are straight cut (because it's simpler/cheaper/smaller/easier) and straight cut gears make that noise

How fast do Skiers go?

Not Olympic super downhill stars, or those nutters in aero helmets doing 100mph+ - just normal, everyday man-on-the-piste skiers?

I like to Mountain Bike, love it in fact - and lots of the Ski Resorts become Mountain Bike resorts in Summer - my workamtes who Ski always give me funny looks when I mention I'm off to Whistler or Morzine in the middle of summer - you can see the anguish on their face that I'm wasting the trip because there's no snow.

One thing they all say though is Skiiing is much faster, even on a super fast course 40mph on a Mountain Bike is flying and you might only hit that for a second or two on a really fast bit - you can go faster on a long Alpine road say, but with the big tyres and MTB's being about as aerodynamic as a brick even the steepest, longest road means 45, and that's way, way past the point where pedalling will help you.

Not that any of that matters really, an MTB at 30 off-road feels a whole lot faster than a Sports Bike at 130 does, but my Skiing mates all scoff - "I do 70 on skis easy, 80 in a tuck".

Im happy to be proved wrong but i doubt they get anywhere near 70-80! When i snowboard it feels fast when i straightline it but i presume im only doing maybe 30-40 max on the biggest hills. No chance they do double that!

Unless you're mates with Graham Bell, in fact even if you're mates with Graham Bell, in fact, especially Graham Bell, they're having you or possibly themselves on.

The average punter on the piste will be doing no more than 30-35mph on a really good day. Once you take into account traffic, lie of the land & hangovers, more like 20mph.

Pears: how do they transform from turnip-like unripeness to rotten mush without ever seeming to transition through 'ripe' first?

a good skier going down a normal mountain would be struggling to top 40mph

I'm an average skier.

Looking at my SkiTracks app, the max speed I hit in my one week skiing this year was 78.6kph (48.8mph) and the average was 16.5kph (not sure how the average is worked out - does it include standing around, going up on lifts, etc.?). I hit 70kph+ most days.
