Get a scraper/brush and keep it in your car.
Use it before you start driving. Don’t just clear a “porthole” to see out of. Clear the snow off the roof too. If you don’t it’ll fly off and hit the guy behind you or it’ll slide down over your windshield.
If you don’t have your scraper, a credit card will work in a pinch for the windshield.
Don’t pour hot water over your windshield to melt ice. At best it just doesn’t work, at worst you’ll crack the windshield
If you’re new to driving on icy/snowy roads, get a sense for how/when your car will break traction. Find an empty parking lot, accelerate a bit and then brake increasingly harder until you start to slide. This will give you a feel for the conditions under which you’ll lose traction to brake. This is also a good way to learn how to recover from a slide.
Didn’t you literally say you were offended by some people you don’t know choosing to go to Laos…?
