Ooh, smart!!! I have something called a sno-brum (pronounced broom) that's a sturdy foam rectangle at the end of a telescoping metal pole (it's on my driver's seat right now, so I can grab it EASILY in the morning!) Now, granted, I have a sedan - but I'm just barely over five feet tall... and yet, this device enables me to push snow off even the roof of the car.
Now if I could just remember to get an ice scraper...
