$50 (£35) is probably less than it costs for my Wife and I to go to the cinema, once you've factored in travel and babysittings costs.

I wish the gun control debate in the US could get beyond the 'do more guns result in more people getting shot?' question, and move on to 'Okay, so more guns means more people getting shot, but guns are important to us, so can we just discuss what level of people getting shot are we prepared to tolerate?'

It just seems so dishonest otherwise.

Thank you. That's a very informative post.

The world currently creates about 56 million passenger cars per year. A Tesla battery contains around 21kg of Lithium in it, so to switch all passenger car production over to lithium batteries, we're looking at in the order of one million tons of Lithium required per year, meaning production would have to ramp up by a factor of about 30, and we'd only have proven reserves for the next fourteen years.

There's something like 32 million commercial vehicles made a year, and if we assume they need a battery on average close to twice the size of a passenger vehicle then we'll need 2 million tons of Lithium a year, (a 60x increase in production) with proven reserves to last us seven years.

And that doesn't really figure in all the other places we'd start using batteries if we moved entirely away from fossil fuels.

There's a bunch of speculation going on in this thread based on personal anecdote... let's have a look at some data shall we?

Let's compare the ngrams of the words 'bespoke' 'customized' and 'customised' between the USA and UK:

USA: http://tinyurl.com/usabespoke
UK: http://tinyurl.com/ukbespoke

You can see that in both cases bespoke had its primetime in the first half of the nineteenth century, falling off and hitting its nadir at around 1980, with a resurgence in usage since then.

However, it's also clear that the usage of 'bespoke' is more common in British English than it is in American English, although not by a huge margin - current usage (in books) is about 70% more common in British English than it is in American English.

Obviously the huge cavéat here is that these ngrams describe how language is written in books, rather than how it is spoken.

In central London where these routes are being constructed, you'll find very few "elderly, young or poor" driving anyway. There's already a congestion charge to pay if you drive in the centre and there's very few places to park. Very few people commute by car into the centre as there's almost no parking so the only people who do tend to be people who are sufficiently high up in a company that they can persuade their company to pay for a parking space. This is a city in which you can sell a garage in the centre for over £100,000. As a result, the vast majority of people commuting do it by tube, bus, bike or walk - or perhaps some combination. I get a train to London Bridge and then take a hire bike to the office. Most of the traffic I see during the rush hours is made up of:

* Buses
* Construction Vehicles
* Black Cabs
* Delivery Vehicles
* High-end hire cars

My guess is that folding wings & landing gear would be heavier and more difficult to produce. Also, it would mean you'd need a landing strip to land at, which would mean it would have to fly over land; probably a harder thing to get clearance for.

Firstly, I think SpaceX were trying to get away from parachute recoveries. The Shuttle solid booster rockets used to parachute down into the ocean, but the problem with that is that they need completely cleaning out and refurbishing between each flight.

Secondly, they would need more than parachutes to recover the first stage because it is travelling so fast when it separates (not sure of the exact number, but somewhere between 2 and 4 Kilometers per second). They have to do a retrograde burn to slow down enough to safely re-enter the atmosphere.

The thing is, I'm not sure the vast majority of people do still use those imperial units. UK schools have taught in metric units for the last 40 years, and all food and drink (with the exception of draught beer and cider) has had to sold with metric labelling for the last 20 years. I'm 41, and although I have a good idea of what an inch and a foot is, I have no particularly intuitive feeling for a pound or an ounce, so I always have to the mental conversion to grams or kilograms first, and I grew up at a time when imperial measured labelling was more common.

The thing I find interesting is that David Cameron is probably among the last set of people in the UK to have been taught any imperial measures in school - in fact he would have been eight years old in 1974 when using metric units in schools became compulsory, so it's possible he could have been taught both imperial and metric (Unless private schools were exempt from such rules, I guess).

Certainly anyone aged 44 or under in the UK will have grown up with the metric system in school.
