What should I fill a hole with

I was thinking some concrete and a steel post. Now when they're too lazy, they can proudly wear the scar on their vehicle.

I filled the hole up today. Ended up using asphalt patch since I decided concrete would be too much work. 450lbs in total. I also uploaded a couple pics to show you the area a little better. Also a pic to show why it isn't an issue on the other side.
