What possible advantage is there to flat roofs? I stayed with friends recently and they have a flat roof which has a lip about an inch high all the way round and it just had a layer of water (and ice) on it for the entire time I was there. I just don't see how not having even a slight slope can be beneficial? Why wouldn't you want water to drain away?
Every time I see a flat roof on Grand Designs I yell out "Don't do it; it'll leak!" And it does. Every time. I don't know why Kev doesn't point out this basic fact, but he's probably too busy knobbing the distaff side of the featured designers.

One of my favourite ads used to be the bloke that looked at the camera and virtually shouted "Got a flat roof? Let's face it, it's going to leak.". Then they obviously got some complaint from the honourable company of flat-roof installers or whoever, and had to tone it down a bit, so they got a voiceover man with a completely different voice to say "might" and roughly overdubbed it where the original said "going to".

True, but there are definitely different severities. I've met people who just cannot process text on a page, but also others that just have trouble on the maths side, or parsing complex written instruction. IMO from a schooling point of view though, it should be a boolean. You are, or are not dyslexic.
I think the severity all depends on the coping Mechanisms in place. I was dyslexic at school and it was put down to laziness (as it so often is). It was only during a college access to university course did the tutor notice the gulf between my written work and the answers i would give when asked a verbal question. The extra help is useful come dissertation time when you have to write circa 10K words AND make it make sense. A persons ability to cope can often influence how bad it seems

Why has it become almost impossible to tell what engine, how powerful or fast most cars are these days? It used to be the case of seeing the badge on the back would tell you everything you need to know.

Why, when a vending machine refuses to accept your perfectly good coin, does it accept it after you have rubbed/scraped it against the metal of the machine?
I don't think the rubbing does anything, instead I think that once you've taken it out a few times out of frustration, you'll load the coin slightly differently and it will "catch" on the part of the internal mechanism that for whatever reason, it was missing on the previous attempts.
I can’t see it, today for example, same pound coin, put it through 5 times, some soft, some hard, some twisted, nothing. Rubbed it on the machine, worked first time.

Might be this particular machine, but it does it to me a lot, way more than could just be coincidence.
I pop them in my mouth then try again in the machine. Invariably works. Slightly underweight perhaps?

In arid climates it lets you walk around on the roof and is probably cooler as the sun will have less to hit.

No idea why you'd want it in Britain!
Cheap to build
Granted, but surely it can't cost any more to put a tiny slope on it?
They do have a slope on them (correct term is 'fall'), you just happen to have seen a faulty one.
Don't fall into the trap of getting flat mixed up with slope, fall or not level, they aren't the same.

Driving past Aston Martin on the A40. Lots of very nice cars on display, got me thinking.

As a guestimate, how much stock of ( monetary value ) is held in England of new and used cars. It must be massive, all the way down to small traders with 3k cars on their forecourts.

With the bigger dealers who owns the cars. I know many dealers have access to stock of other dealers. So I guess the Motor group own the cars Jardine etc. Must be into the 100 million ? 1 billion ?

With the amount of germs that live on coins I'll pass on that technique, thanks.

I was curious, so did the (very rough) maths, based on some population figures I got online so not sure how accurate (also population density might not equate to car sale density, but it's the best I could do).

Average population density of Britain is 650 per square mile.
Redditch has approximately the same population density.
There are 336 trade cars for sale on AutoTrader within 1 mile of the centre of Redditch.
Getting an approximate amount for each of the 34 pages (10 cars per page, sorted by price, taking the 5th car's price and multiplying by 10), then adding all the pages together..... The value of cars within a 1 mile radius of Redditch is £8,581,300.
A circle with 1 mile radius has an area of 3.14 miles. Britain has 80,823 square miles.
80,823 / 3.14 = 25,740.
25,740 * £8,581,300 = £220,882,662,000.

Answer: 220 billion.

Huh?

Being a car fan I used to know stats for most cars on the market, or that a 1.6 Capri wouldn't be as quick as a 3.0.

That's all rather difficult if you have no way of knowing what engine a car has, which seems to have become rather widespread.

Hope that helps.

I'm with you on this Marshy. It all started when manufacturers started offering the "delete badge" option and buyers - through some kind of reverse snobbery or something - didn't want the world to know how big their engine was. Quite the change from the '80s and '90s "GTi 4x4 Turbo CDi GX Ghia Limited Edition" days when even automatic cars got a proud badge on the back to let everyone know the driver didn't swap his own cogs.

but you have a smartphone and the reg yes? https://www.gov.uk/get-vehicle-information-from-dv...

there is a golf that is parked up the street, twin exhaust like an R but the brake discs arn't that big, no badges, that website plus the reg and manufacturer tells me it's a 1.2 frown

Answer: 220 billion.
That would imply 336 * 25,740 = around 8 or 9 million trade cars for sale in the UK, about a quarter of the total number registered. Implying that Redditch, while average in terms of density, is somewhat above average in terms of car traders. Possibly more rural areas don't have the passing trade and more built up areas are expensive for car lots, so middling density is ideal.

Hmmm....
An alternative methodology. Let's see how we go.
Autotrader has about 80% market share of used.
480k cars on it right now.
So inventory of available used is 480/0.8 = 600k.
On the app it helpfully splits them by price.
2k under £500, but 75k under £3.5k etc...
Weighted average comes in at £11,500 or so.

So the used inventory is worth around £7bn.

For new, we know that 2016 saw 2.6m new cars sold, but it's hard to find the average value.
Let's guestimate £15k (ex-VAT).
As for inventory I checked the Inchcape numbers and they have roughly 20% of (ex-VAT) sales in inventory most of the time.
So if that applies to the market as a whole then the new inventory is 2.6*15*0.2= c.£8bn.

Oh yes, that's much more convenient than - oooo, I dunno - just looking at the badge on the back, especially if you're driving at the time...
