Slippin' 'n' slidin'

Stuff you can't do with a car during a blizzard:

• Brake (unless you decelerate with the clutch; by the way I think I broke mine)
  
• Steer: when you go left, you go straight; when you right, you go straight; when you go straight you go sideways...
  
• Accelerate
• Park: you can't stay still long enough to park in any meaningful fashion
• Overtake
  

Basically, all the stuff a car is supposed to do to get from one location to another.
