I've always been impressed with how OHP helps stranded motorists. I think it would vastly improve the image of city cops if they did the same sort of thing. I never even see them stop to check on stranded motorist. They typically drive right on by. I'm not sure if it's a policy thing or what. I know they're not paid to provide free roadside assistance but I would think anything they could do to endear themselves to the communities they're in would be worth while.
Several years ago my car broke a timing belt on SW 104th in OKC. I called a wrecker and the wife and I were waiting with the 4 way flashers on. An OKC officer stopped behind us to see if we needed any help. When I told him a wrecker was on the way he said he would stay in back of us with his overheads on so someone would not rear end us.
Another time we were involved in a bad wreck. After trying to reach some neighbors to come and pick us up without any luck, a Mustang officer offered to give the wife and I a ride home.
