So, I hit a vehicle stopped at a stop light...?

I haven't seen anything like this when looking through a lot of the already answered questions about hitting cars. The question is simply this: I accidentally hit a trailer (with a car strapped on it for transportation. It wasn't a semi trailer, but a small truck trailer.) and I acknowledged my demise. Knowing that I shouldn't hit a vehicle and run, I wait for them to pull over so I can talk to them. I didn't get the license number (stupid me... I didn't have anything to record it anyways) and they had many chances to stop. After about 10 miles, I am still waiting for them to stop. Along the way, many open places were available that could accommodate the truck and trailer very easily. I don't know exactly what to think. They never stopped. My vehicle wasn't damaged at all and the back of the trailer looked normal from where I could see it. Nothing looked damaged. What should I expect now?
