Many years ago, I came out from my first apartment to find a Chevy Vega using my Ponton's front bumper as a parking brake. As I needed to go somewhere and had no plank handy, I simply backed up and the Vega gently rolled up on the curb and 'parked' there.
(I wonder who would have been liable if the Vega had kept going and caused some damage?)

Happy Motoring, Mark
