Fun fact: I passed my driving theory test first time. One of the
questions was this:
[Picture of a sign. It's red, octagonal, and says "STOP" in large white
letters in the middle.]
What does this sign mean?
A. Stop.
B. Stop if there is traffic coming.
C. Stop if you feel like it.
D. Go.
I'm not kidding. That's really what option C actually said.
I can see somebody geniunely thinking that B might be the correct answer
I suppose. But beyond that, the only sane reason I can see for this
question even existing is that some applicants might be so bad at
English that they can't actually comprehend road signs. Certainly there
are plenty of signs far more obscure than this.
(For example, a blue circle with red edges and a red cross through it.
Wanna take a guess what that means?)

I didn't actually check the rev count, but in 5th gear, the car seems
very reluctant to go much faster than roughly 65. Which means that if I
want to drive on a motorway, I literally *have* to switch to 6th -
difficult as that is. If it weren't for this, I probably just wouldn't
use 6th at all.
Like I say, in 1st gear, accelerating generally isn't an issue, no
matter how whimpy your car is. It's when you're zooming down a motorway
that there's no acceleration left, so that's where I would have expected
extra gears to be added.

I see... That would explain the statistic about the Bugatti Veyron only
needing 100 horsepower to get up to 100 MPH, but needing a further 800
hp to get up to top speed. (Or something like that.)

Ah yes, F1 cars, the ultimate example of engineering in the raggid edge. :-)

Haha, I drive an 18 year old 1.1L peugeot (also 5 gears - there's another data
point ;-) and regularly exceed 65mph in 4th - indeed, it's often the only way I
can get up to motorway speed quick enough on certain slip roads!

It seems your car is just badly designed then, in most cars I've driven at
65 mph you can easily switch down 1 or 2 gears to get more acceleration
without going anywhere near the redline of the engine. In fact in my first
few cars you *had* to do this when the motorway went up a hill, otherwise
you'd gradually come to a stop! MAybe you were in 3rd gear instead of
5th... It seems to be that in 3rd gear you'd get stuck at about 65mph and
not be able to go much faster - I'll try it on my car on the way home :-)

Yup, if you want double the top speed you need 8x the power!

yet into that category, here's another useless tidbit: I don't drive cars. I
don't know how and I don't give a damn, I just take the bus or subway.
I suck at driving even at games so I thought I'd be putting people's lifes at
danger behind a wheel. :)
so, there you go: a highly useful skill you've got and I don't. should make

My 4-gear Peugeot 1.1 seemed happy to do 60 or so in 3rd gear. But then,
while it had a small engine, it was also pretty light too...

So you live in a place that *has* busses?

If driving a real car was anything remotely like driving that "thing" in
HalfLife 2, most of the population would be dead by now!

Heh, I don't know about that... but I *am* going dancing tonight. ;-)

Random unstoppable craziness:
http://en.wikipedia.org/wiki/Bugatti_Veyron
"At a constant 155 mph, the Veyron is using approximately 270 of its
1001 horsepower; the next 100 mph requires 730 additional horsepower."
"The tyres will only last for about fifteen minutes, but it's okay
because the fuel runs out in twelve minutes."
"2.46 MPG"
It has square pistons, 10 radiators, 4 turbochargers, 64 valves and a
total displacement of 8 litres. Truly, this car is ****ing insane. o_O

It's the age of the car. Go try to find a 64GB disk drive on the shelves
today. As technology progressed, more gears got easier to build in, so they
did. It makes the ride smoother (on an automatic) and more efficient on a
manual.
I tended to skip gears when I had a manual transmission, often going from 2
to 4 for example.
