Subaru's Symmetrical AWD is the best thing in the world at the moment. Also, warning: !dev

Tl;dr: I'm getting another RPi3 thanks to awesome engineering.

Got a couple of inches of light snow here, and on my way home I came across a GMC Sierra dually stuck at the bottom of a moderately sized ditch. Naturally, I stopped by in my Forester and offered to tow it out.

With my 20ft tow rope stretched to its full length I was barely touching the road. He signalled that he was ready, and I gunned it. Slowly but surely the truck crawled out of the 6ft deep trench. She crested the hill with much applause (from me and the driver of the truck). As a thanks, he gave me $30.

Looks like I'm gonna get a new Raspberry Pi to play with. I think I'll turn this one into a countertop MAME arcade machine.

And for those of you wondering why I'm praising Symmetrical AWD as opposed to AWD in general, here's a quick lesson in drivetrains:
Most all wheel drive cars power the front wheels most of the time. This saves on fuel economy. The thing is, power is only transmitted to the rear wheels when the front wheels start to lose traction. At that point you're already screwed; only two wheels at any one time are putting useful power to the road.
Symmetrical AWD systems, like you'll find in all Subarus and most performance cars, distribute the vehicle's torque eaqually front-rear at all times. So instead of waiting until the front wheels start slipping, all of the wheels are powered right off the bat.

To make this more devvy: grrrr php, vim is best, I configured the tab key to enter four spaces, js has too many damn frameworks and they're still being pumped out faster than rabbits in a bunny farm.

    I have a polo gti, you dont need 4wd if you fly over the snow

    @BindView the only advantage awd gives you in snow is better acceleration (or in this case, better power delivery when extracting a vehicle from a ditch). Once you're up to speed in any car it's just about maintaining momentum and stability, which for everyday driving the techniques are pretty much the same no matter the drivetrain

    You just gained a sub! So hard to find other devs who give a shit about cars.
