Two lessons for driving in snow/ice:

1. In a parking lot, clear behind the car, and just enough to get inside. Then back the car out of the space, clear the car off, clear the parking space out, put the car back in the parking space and clear everything you knocked off. If tried without pulling the car out of the space, you'd be trying not to ding up your neighbor's car, clearing in tight spaces under the car, and then doing it all again when you clear off the top of the car into that narrow gap.

2. Don't drive unless you absolutely need to. You may know what you're doing, but others almost certainly don't. But do make sure to clear out at least one car, just in case there's an emergency.
