I do have the 'instant heat and lots of it' units installed.

Nice in the cold, but more importantly your engine runs much
cooler on hot days or at speed without all the lower baffles.

There is, or used to be available accesory gas heaters for aircooled
VWs.

On paydays, people doing donuts in the parking lots, getting out of
Dodge.

Sure you can! As long as you don't have a SAAB with the e brake on the
front wheels (Actually, you CAN, but it ain't easy)

Just get up some steam, turn the wheel, hit the e brake until you start
the spin, let off and hit the gas! Simple!

Now, in your FWD car, do this for minutes on end, without pausing unless
you stall the engine or end up in the ditch...

Oh, that's much different. Never mind...

In my observation, FWD has a traction advantage as long as you:

1) go in a straight line
2) start off slowly
3) don't abruptly change speed
4) don't encounter changes in traction (like, traversing ruts in the
snow)

In my observation, FWD loses the advantage as soon as:

A) you turn the wheel while moving - Toe-out on turns makes the wheels
fight each other. In slippery conditions this means breaking
traction. Also, a wheel only has so much "traction". Instead of
using 100% traction for one purpose (driving or turning) you're
splitting it between the two. Something's going to give. It doesn't
mean understeer every time, but it makes it more likely. This is
further compounded by combining the driving axle, steering axle and
most effective braking axle.

B) take off too hard and shift the weight to the rear axle. Not
exactly game over, but this is why you see people at stoplights
spinning their wheels so much. They seem to think that more gas will
make them go faster, when the opposite is true.

C) fail to match wheel speed to road speed, which is something that
takes skill, and even skilled drivers have minimal feedback to tell
how well they are doing. This means you may need to accelerate down a
snowy hill with a curve in it. In RWD you can let the foot off the
gas, and your rear tires may slide a little, but they'll also slow you
down. Any oversteer you get out of it will likely be slow and easily
correctable. This will be very different if engine braking breaks
traction on your steering wheels.

D) have the road surface change under one drive wheel only- this can
cause torque steer, disrupt your momentum or even yank the wheel out
of your hands. If you are also turning, you could have sudden and
violent shifts between understeer and oversteer. Probably not
complete doom and gloom at 25mph, but for the paranoid drivers that
freak out at the smallest thing, this could mean them going up on the
sidewalk and ruining a pedestrian's day.


But I'm not an engineer. I could be smoking goodyear freckles in a
water bong filled with burnt Type F.

You're not too far off, and mentioned a lot of mistakes all the Marios
make in the first snow storm.
