I love the old 50cc bikes - they're all absolutely stunning. Check out the gallery here:

I think you'd want to try a Dodge Ram's horn...

If you have a genuine photograph of Salinger, it'd be worth a damn sight more than $1500.

But I wouldn't have to worry since they wouldn't make it round a blind corner in the first place.

I left my reply for a while to try and find a politer way to put this, but the best I could manage was:

AWD doesn't give tyres any more grip, other things being equal. Since brakes act on all four wheels anyway, 4wd offers no advantage unless you can't brake smoothly. A gentle right foot is better than all the technology in the world.

Just like car design, aircraft design is a compromise between what's optimal from a performance standpoint, what's optimal from a passenger's perspective, and what's optimal in terms of cost.

To put it in its proper context, the Audi 5.0 V10 TDi makes 350bhp/627 lbs/ft, and the 6.0 V12 TDi manages a somewhat ridiculous 500 horsepower and 750 lbs/ft of torque.

Diesels aren't becoming obsolete exactly, but the new generation of petrol engines is matching diesel for power, and economy in a much smaller, lighter package. You'll notice I didn't say they're matching the torque figures, which is why diesels are still better in some applications.

It varies across Europe, but quite a few big countries, including the UK, have higher tax on diesel than on petrol. It's not just about fuel economy.

Oh, also you reminded me of the old joke about the German policeman asked for directions:

It's definitely Australia - the land where absolutely everything tries to kill you.

I don't normally correct people's grammar on here, but you just made my head hurt.

It wasn't that he was swearing. More that when you ask your wife if she's ok and she says yes, you shouldn't appear to swear at her answer :)

Top tip: if you are in a car accident and ask your wife if she's alright, when she replies that she's alright, your next word should not be 'fuck'.

"Considering functionality and ease of service, I don't know why more carmakers didn't always go for four-wheel discs, or why they still use drum brakes on some cars."

1) Be gentle.

Plenty of torque at low revs is very useful for snow-driving. RWD is more of a problem, but if you're gentle and keep to slow speeds you'll be alright. If you find yourself doing 180s, either slow down, or speed up so they turn into 360s ;)

"You wouldn't be able to go up a steep hill"

No, that's not the case. The worst tyres in the world will offer at least some grip on snow. If you're gentle enough you can drive on black ice without sliding - on the flat, of course.
