Ah, now I understand the question better.

If I thought assisting might be lethal to me, I wouldn't do it.

A situation can be potentially lethal to some folk but not others.

An unconscious person (frinstance) sitting in a crashed car with petrol
dripping onto them is a lot more at risk than a fit, conscious,
reasonably well protected person who may remove them from the car.

As regards any legal requirement to assist, I don't care.

I believe that I have the brains to assess a situation and act accordingly.

Have a look at my garage sometime... there are several good examples :)

You'd have a light drive. :)

Makes absolutely no difference on my pushbike when I turn the lights on,
doesn't make it any harder to peddle.

As for the original argument, in the real world, as opposed to this
place, any additional load from an average set of headlights would make
absolutely buggerall difference, the average WRX has more power drain in
each of the 12 subwoofers in the boot.

Now turn the aircon on, and thats another story, a much cooler one

I think you've been reading too many physics books and you've lost sight
of reality. Are you saying that if I measure something once per second
and then multiply that by 3600 my result is not an accurate measure of
an hourly rate? Do you think the computer controlling the fuel rate
just guesses?
The flow rate actually updates much more often than once per second. At
a guess I'd say it's updating about 3 times per second, and at idle or
on the flat while driving it remains steady, which I think would
indicate that it is not just making a prediction but accurately
reflecting the fuel flow rate.

As for it's ability to reliably indicate what's going on.. if the engine
management computer controlling the fuel injection system doesn't know
what's going on you better start writing some new physics books to
explain how exactly it all works. Maybe it uses the same magic to
control fuel flow that it uses to power the headlights.

If it's measuring 2.68l/hr once per second that would be umm...
0.0007444L/sec.. I reckon it updates about maybe 3 times per second
meaning it's measuring 0.00024815L/sec. I would have to check your
physics books to see if that is near enough to a poofteenth or not, I
reckon it is probably pretty damn close.
