Took a ride on car hood/road rage

Sunday night I was involved in a road rage incident right next to the quarry near Dinkytown. Guy attacked my roommate and then tried to run me over when I was about to call the cops. Ended up on the hood. At no time did he slow down only continued to speed up. I ended up braking the windshield while pounding on the window and as i flew off the car I believe I seen a small amount of paint taken the hood. It was a suv style white Mercedes. I failed to get a license plate as he drove away. Believe the license plate begins with LG but not sure. So if any knows anything could ya let me know so this guy can go to prison instead of being on the road I’d greatly appreciate it.
