First, glad it wasn't any worse, you will heal w/no issues I trust. Too-bad no one got the info on the car. I am always watching out for that kind of behavior. You wouldn't want to try to stop anyone, just get close-enough to take a tag & call 911, and wait until the PD showed-up. "Leaving the scene of an accident w/injuries, rider ejected" is what you want to tell the dispatcher, after the tag # & direction the car is going. Common sense stuff. Following the driver could create a confrontation or result in you having an accident yourself. That's a judgement call every witness is going to have to face when the time comes.
Yes, unfortunately, whether in a car, truck, or on a mcy, you can probably count every day on having some bonehead (oops, sorry!) er, numbskull hazard you. Be vigilant and be careful.
I was in your general neck of the woods awhile ago. At the end of last summer I went to MI to Oxford township to visit my GM Design buddy from college in MI and while he has a good range of tools, he had never picked-up an air compressor. I searched CL until I found one for him in Burton, the other side of Flint from you. We took a ride over there & I paid for a used 20 gallon 110V Craftsman rollaround compressor for him. He has a CBR600F2 he commutes to Warren MI on when the weather is nice. He lives on a lake that backs-up to Bald Mountain State Recreational Area. We ride mountain bikes from his house onto the grounds of the state park, some great riding to be done.
Once while over there, he pointed to a cabin for rent in the park & asked, "know what happened there?"
"No," I replied.
"Jack Kevorkian had a customer who left this planet in that cabin," he said.
