Don't use plastic ice scrapers, they're absolute shit compared to the alternative: Brass ice scrapers. At least an order of magnitude easier to get ice off windshields with these things, and they don't damage the glass.
On top of the other comments, a brass blade ice scraper will change your life. I moved from TX to PA, and got this on top of a brush to wipe off the heavy snow.

This little gem has completely eliminated this problem. Best scraper I have ever used hands down. It has a thin copper blade that works great with those moderate to thin layers of ice we get.
