Could I be charged with a crime for having a friend take me to the hospital immediately after wrecking by myself?

I wrecked my brand new motorcycle on my home road the day I bought it. No one else was involved and I was sober. And although injured, I was fully perspicuous. I called my roommate who was at home less than a quarter mile from the scene and asked that he take me to medical care; I cannot afford the ambulance ride and made clear that I would refuse it. In the mean time a neighbor called 911 and then blocked the road with a vehicle and stopped my roommate from leaving (by this time I was already in the car, but the neighbor held my door firmly open when my roommate tried to shut it). The cops then came and forced me to wait for emts. After elucidating my situation and preferences to the emts, they had me sign a release and let me go. It all amounted to red tape while I bled. I live close to the hospital and definitely could have gotten there by other means before the ambulance arrived if not fettered. Could I cop a charge if I had left? I planned on reporting the accident from hospital.
