At one point in my life, I moved from mild weather in the southwest to places where it snowed a few times a year.
If my new friends and neighbors had given me some newbie advice, it could have saved me lots of money and effort. That being said, I noticed some things when I was driving a snow-plow truck about three times a year.
In the neighborhoods that were mostly populated by retirees who were familiar with the local characteristics, there was a pattern. Any car in a driveway was packed "nose outward", and the wipers were sticking up like antennas.
For those who are new to snow, when you go to clean the snow/ice off of your windsheild, it's easier if the rubber wiper blades are not frozen to the glass.
As far as backing-in the car. If you back out the driveway on a normal day (*which is likely sloped to shed rain), then you must come to a stop and change the transmission from reverse to forward. There are rare times when the road in front of your house is slippery (*and might also be sloped uphill) and you just sit there spinning your tires, while the lubricant and seals in your differential are cold...not good.
If your car is pointed out, you can get in, put the transmission in drive, and hopefully slide out into the street while carefully maintaining forward motion until you make it to a well-groomed street with better traction.
I have a second set of keys for every car. I can start the car, and then lock the door with the engine running and the defroster blower on max, while I go back into the house to make a warm cup of coffee. When the time arrives, I can get into a car where all the windows are free of ice and snow.
As to snow in the driveway, if you drive on it even once, it gets packed into a form that is similar to ice, and is difficult to shovel. Immediately after a fresh snow storm, the snow is typically dry and fluffy, easy to shovel. If you wait even one day, the partial overcast sun will partially melt the snow and then it will freeze overnight into ice.
Stay off the driveway, and shovel any fresh snow every morning, even if it is still snowing. Using an ebike with a DIY snowplow blade is brilliant.
