A snowHead

livetoski, Fingers crossed! Sad

Well, the person's real but it's just a made up name, see?

finestgreen, My creaking analogy is, I think, adequate in this case as it's not just our mass that increases but also our dimensions and although my maths is horribly ancient and I could easily be wrong the proportional change is a logarithmic progression along a curve. If we all fell and landed curled up in a tight ball then yes you would be correct.

livetoski, bad news but always fingers x'd for him Confused

Another point worth noting which might explain why ACL is more of a problem for adults is that children will have their DIN set to release earlier. Which goes back to what Masque was saying.

Then you can post your own questions or snow reports...

Masque, yeah, I know what you mean, just not sure about logarithmic. I suspect as soon as you get beyond F=ma it becomes much much more complex.

Incidentally, interesting study:

http://www.ncbi.nlm.nih.gov/pubmed/22427619 - "Female skiers showed a 2-fold higher risk of suffering from an ACL rupture on their nondominant leg"

So, might be a good idea to make sure your fitness routine isn't biased towards your dominant leg.

Well, moving on from the ACL thing, I do have a product that I would like to see invented, and that wouldn't even be a bit difficult using existing technology.

A back window inexpensive tailgater camera. It would have two cameras - one points down at my rear bumper, but has a wide enough angle to catch the driver behind's bumper, and perhaps their registration number, another points towards the front of the car behind and captures the registration number and a picture of the drivers face. It has a sensor from my speedo that when I click a button, it records my speed, and takes the two photos at the same time. It also has a reasonably accurate distance sensor just to back up the photos.

Then I can foward the data to the relevant authorities, who can issue a £60 fine and 3 points for dangerous driving. Of course if they contest it I might have to stand up in court and swear that the camera image and speed are accurate. But I'd do that, no problem.

It would also come with a big sticker to put across my bumper that says "Warning! Tailgating Camera Fitted!" so that people know that tailgating me would result in a penalty.

If someone could come up with inexpensive technology to do it, I reckon that the various authorities would go for it. After all they love handing out speeding tickets, and this way people like me become their roving reporters in the field, saving them on the need to have lots and lots of expensive traffic police pulling people over.

Plus I get my own back on the utter twunts that spend their time on the M25 tailgating me when there are three lanes on my right that they can use, but driving very close to my back bumper makes them feel like they are Lewis Hamilton, presumably to make up for the deficiencies in the rest of their sad little lives which we both know they aren't.

VW Golf drivers take note, you are rapidly becoming the new Audi drivers of the roads, who were previously BMW drivers. We understand you've had your company car downgraded, but it doesn't mean you need to crash the sodding thing to get back at your employer or life in general.

In addition to this, like Crimestoppers, I should get a reward for my hard work. £20 from each driver convicted should come to me to make up for the cost of buying the kit. If the kit was £200, I think I'd have my money back inside a month on the M25.

Monium, amen brother, almost followed a guy home yesterday when he came up to within about 2 feet of my rear bumper at 70. Sure fire way to send me into road rage. Camera would be awesome - or maybe just the sign would be needed

snowHeads are a friendly bunch.

Monium, floor your throttle and hit the brakes hard at the same time with a little wiggle on the steering . . . should make then cack themselves Twisted Evil

The camera technology exists. The new Contour will do all you want. Bluetooth remote control and GPS module to capture speed and location data. Fitted one in my truck and used it twice to get out of a ticket for me and to get the offending drivers into some deep poo with the Smokies Twisted Evil

Masque,

Masque, I quite like considered use of the fog lights when they get really close, which gives them time to back off a bit so that I can brake to a safe speed for the distance they are behind me. Sadly for some, the distance they have left allows me to drift all the way down to 40mph before it is safe. They don't seem to like this, at which point they attempt to undertake.

The difficulty with a single camera or videocamera is that you need to capture quite a lot of data for a driver to be prosecuted, and if I walked into a police station with a memory stick they'd laugh me out of the place. What I think they should do is set up a simple black box with a couple of diddy cameras fitted so I can just push a button to catch the info required for prosecution. It would become like getting a speeding ticket, fixed penalty issued once the images had been reviewed by the police, if the driver contests it they are going to court and I am a witness for the prosecution.

I don't think I've ever seen or known anyone get prosecuted for tailgating, but on motorways it causes a vast number of accidents and pileups every year, where people just can't stop in time to not hit the car in front when they have to stop in an emergency. Speeding, on the other hand, causes some accidents, but I would wager that someone driving at 85mph on a motorway is less risk than someone who routinely tailgates.

You know it makes sense.

I really really enjoy messing with tailgaters. Slowing right down (to single figures sometimes) when there is no possible chance of them overtaking, and then absolutely gunning it on a long straight with no oncoming traffic. Then when they eventually overtake and look at you furiously, doing a massive ridiculous Cheshire Cat face or blowing them a kiss.

Otherwise you'll just go on seeing the one name:

Of course the dream ticket is to enrage them in a perfectly time way, so they do an over-limit overtake past a speed camera.

Not managed it yet.

Monium, i'm sure slowing down to 40mph on a motorway would be seen as dangerous driving as well. My advice would be to stop taking things so seriously, speed up or move over.

Fun fact, when I used to live in Germany I got in trouble for tailgating and had to go to one of those courses which is like AA but for speeders and naughty drivers. All cause in Germany they have distance cameras. Sadly I got screwed over as the two guys in front of me on a two lane motorway emergency braked thinking it was a speed camera.

Where are all the snow related inventions I can go and steal ? Come on guys Sad

red 27, fat chance. You need something that throw in a happy ending too. Little Angel

I would like googles that can see through a white out (fog or snow), or flat light and display the actual slope that is below the precipitation. There must be some sort of beam that can cut through the crud in the air or lack of reflected light to show you where the slope goes.

laundryman, I knew you'd be along soon to explain it in a clear and concise manner Toofy Grin

Yes you're right the increased impact to extremities away from the central mass is exponential by mass/speed/distance
The central mass would be linear
And the ability to withstand the above is logarithmic

All cleared up snowHead

Still means to avoid injury it's less weight, more flexibility, increased fitness and better technique . . . 'Plus ca change, plus c'est la meme chose'

Megamum, isn't that what your feet are for? wink

snowHeads are a friendly bunch.

laundryman, cube of height? I'd have expected it to be closer to square (as that's what BMI uses)

F=ma2 ????

Megamum, I think the only way to avoid the injury would be to imobilise the knee from a twisting action but I fear that would still not prevent injury through an extension type of fall (trapped foot/fall forwards) AND would def. effect one's skiing. Also unless one did it for both knees the chances of causing an injury through imbalance might be higher. That would make the prevention exercise expensive, annoying and uncertain. I think the best bet is that remedial spung knee brace people either slag off or laud on here from time to time (can't remember what it is called). From what I recall that would probably prevent an ACL injury as much as anything else in an acceptable range.

You know it makes sense.

finestgreen, BMI doesn't have any mechanical significance. I guess they chose the square to get convenient bands that they could label. The masses of two people of the same proportions (including internal composition) would vary as the cube of one dimension. A bit of a crude calculation for random pairs of real people, I'm sure!
