Each battery and each vehicle is equipped with a smart card. When you swap batteries at a service station, using a palletised system that'll do it in a minute, your credit card is swiped and you are charged for
(a) the period of time you have used the battery (basically a lease)
(b) the net change in electrical charge of the battery (so if you partially recharge it before returning it you pay less)
and most importantly
(c) the 'damage' you have done to the battery either by overcharging, excessive discharge, or just sheer number of cycles. This damage is fairly easy to calculate.
This has the following knock on effects.
1) A vehicle that is kinder to its battery will be cheaper to run
2) A battery that is more robust will be more cost effective.
Therefore there is a direct economic value in trying to develop better cars and batteries.
Things I haven't worked out yet - how do you recharge the batteries at the service station - does it have its own power station? Or does a big truck deliver 100 new batteries every couple of hours and pick the old ones up to take back to a recharging station?
an odd definition of fast driving. Towing a 1.5 ton horse trailer behind a V8 Ford Falcon we managed 36 hours door to door, for 3500 km, from Melbourne to Darwin.
(a) it all depends on your frame of reference. If you cut a rope that is supporting a whirling object, and try and hold the cut ends together, you will have to supply both an inward and an outward force to keep the whirled end going round. I don't think it is unreasonable to think of one of those as centrifugal force.

(b) let's call "the combination of angular momentum and centripital force" centrifugal 'force'.
Oh, being right is pedantic? Since the moon's gravity has very significant effects on Earth, I hardly think that raising the much more measurable effect of the Earth's gravity on the moon is pedantic.
So piss off you fucking moronic wanker. Since you claim to like that sort of language.
They can't find work in their field (all jobs outsourced)
Why not?
For that to be true there would have to be ZERO jobs in that field (however you define that) in the country.
Usually when people claim this they mean they would have to move, or take lower pay than they think they're worth, else they aren't qualified (in a general sense) to work in that field anyway.
FWIW every new job I have ever had has involved me moving, from a minimum of 200 miles, to a maximum of 10000
EA's objective is to sell games and make profits. IF their profits increased by promoting the names of the designers then I'm sure they'd do it.
My guess is that they tried it, got zero benefit, and decided to devote that marketing budget to something that worked.
Let's face it, there are very very few game designers who have any mass following. To build up a following would require time, not something that is likely to be tolerated in a publicly quoted company these days.
As for peons. Um, well, I guess that is the truth. Working with brains and keyboards, instead of muscles and ploughs, does not, by definition, change your status. If your job involves working on someone else's ideas, with their tools, to their timeframe, then objectively aren't you a peon? Damn, am I?
"If this ever happens to you do not ever attempt to turn the ignition all the way off... In most cases you will lose both your power steering and your power braking. Make sure that you keep it at least on partially as most cars will not lose total power this way."
The engine is either running, in which case you will have power steering, or off, in which case you won't. There is no 'low power mode' which is what you seem to be implying.
The vacuum reservoir in your servo will give you at least one assisted, braked, stop with the engine off.
Both systems still work even when un-assisted, you'll have to push hard on the brake pedal, but the steering will be fine. Few people/need/ power steering in a normal car except for parking.
The reason you don't turn the key all the way is that that will engage the steering column lock. Trust me, it is a very bad idea to engage the column lock while driving.
"If you are traveling at a high rate of speed losing power steering/braking will cause more problems for you."
Wrong, see above
" First try neutral and even a lower gear if for some reason neutral isn't engaging. It's going to over-rev the engine but personally I'd prefer to replace a transmission or the entire engine rather than my blood or organs."
Most modern engines have rev limiters. If you knock them into neutral then they'll just sit at the red line. Not pretty, but not the end of the world. I don't think you could force a manual box into a lower gear easily, but it might work. Many modern auto boxes won't change down until the operating speed is within parameters. Neutral will work for manuals or autos.

Right idea, wrong number.
The most efficient internal combustion engine in the world that I know of is >50% efficient.
The most efficient gasoline IC engine I know of is that in the Prius, which tops out at around 36%, and on average exceeds 30%
If this theory is wrong then why does anyone get paid more than minimum wage?
The market is not perfect, but, as evinced by the pay in the IT sector, over time it does end up with a system whereby the people who make the biggest contribution to the profitability of a company do get paid more, and assembly line workers get paid less. It is not pretty, it may not even be fair, but it does make some sort of sense. Why should a CFO get paid (say) ten times what an assembly line worker (or coder) gets? Because if he screws up he can take the whole company down.
Because frankly we are not interested in anybody's html code writing skills. We are sometimes interested in finding out what they think.

The Citroen system has a reaction time of the order of seconds.
The Infiniti system was about 2 Hz
The Lotus system was about 25 Hz
There's no real comparison between the three. Citreon is basically self -levelling suspension, the Infiniti was probably rubbish (I didn't drive one, just saw the video)), and the Lotus system was the aspirational target.
I have my doubts about the Bose system, but there is no doubt that in principle they may be able to do what they suggest. Just as a cynical viewpoint, maybe those struts are big enough to hold coil springs.
Odd that. Do you own any shares? Do you have a pension scheme?
If the answer to either of those is yes then you are whining about yor own activities, which may be an enetertaining form of self flagellation, but doesn't add much to the intellectual grist.

But that is no worse than a belt driven supercharger, or a belt driven hydraulic power pack, both of which can be installed with no particular drama, and have about the same power rating.
The problem is that you are not comparing like with like.
I'll take an Australina example.
A modern car has catalytic converters ($600) airbags (say $1500) 17 inch wheels, a 240 hp motor, climate control, ABS, CD player and a 4 speed auto box. It costs $A 35000. The median Australian wage is 49000
Now, thirty years ago the catalytic converters, airbags, climate control, ABS, CD player and 4 speed would have quite simply been unavailable. You might have been able to get 240 real hp... but I doubt it, unless you built the engine yourself.
Anyway, turns out a V8 Falcon, slightly less powerful, and quite a lot lighter, would have cost 5567 (I'm not sure if that is pounds or dollars). It rode on 14 inch wheels and had a 4 speed manual box. The median pay was 7228
So, a new falcon without all the 2005 car's gizmos would cost 77% of the avergae wage in 1975, and the modern car is 71%.
So, in this example, at least, you are wrong in detail, and are ignoring the added value in the modern product.

IN Oz we get about 7 kWh of electricity per day from a horizontal 8 square metre panel, of 20% efficient cells is spring summer or autumn.
Worst day I have ever seen was about 40% of that (continuous gloomy cloud).
I'll have a look at the hydraulic layout of typical ABS systems and see if there are any in which that could happen.
I'm inclined to think not, most still use two independent circuits, as that is a LEGAL requirement in most large markets.
Here's the quote from the Bosch Automotive Handbook "Legal regulations stipulate a dual circuit transmission system as mandatory"
By my reading that implies that there should be no single point of failure in the hydraulic system that will disable both hydraulic systems.
Sorry mate, I can't believe someone bothered developing an ABS system for your jurisdiction that broke that rule.
Your car can probably brake at 0.8g.
.8 g the total force is 2500*.8=2000 lbf
At 60 mph, that is 5280 ft/min.
It probably weighs 2500 lb, at
so, since power =rate of doing work, and work is force times distance, power = force times speed.
1 hp=33000 ft lb/min
roll the numbers, you get 320 hp of braking.
So, even at full power, even ignoring losses in the driveline, at 60 mph you can easily slow the thing.
Now, if you were to change gear and try at 30 mph you might find it a bit more of a challenge.
