Dont ask,,,,,,,why its a bad idea to try pushing your car that dont get any tracktion at winter with snow and ice all around the wheels.
And dont put the car in gear,, turn the frontwheels max to the left,, walk out of the car and look how the rear wheels slowly spinning around without getting hold on the icy surface and THEN help pushing the car from behind as much as you can.
Dont think you can catch up with the car if it by this operation luckely get grip and disapper in a crowded street with no one inside the car,,and please,, dont ask me how,,,,
