"If it had been a few seconds earlier ... I probably would have ended up under his front wheels."
Mills said he was immediately helped by strangers. "I lay there for a few minutes getting my breath back and then a couple of people came up and managed to get me off the road. A lady and a younger guy came first and then some road workers parked their ute and put on the flashing lights to stop anyone running me over.
"When they dragged me off the road I was asking what happened and was expecting someone to say I had hit their car, but they were all saying he had taken off.
"I can't believe someone could do that, how could you live with yourself knowing that you had just hit someone?"
An ambulance was called, as were police, and Mills was taken to Auckland City Hospital where his partner, Anna, came to meet him.
While he did not have any broken bones, he is now on painkillers and has to take time off work.
Mills wanted to thank the motorists who stopped to help him.
"I probably ruined their mornings and made them all late."
Senior Sergeant Matt Knowsley said the matter was under investigation and was a reminder for drivers.
"In the Auckland city district motorists share the road with cyclists and pedestrians and need to take extreme care. If you are involved in a vehicle accident, you have to stop and ascertain that the other people involved are okay. If you don't, you could face charges."
