Even if there is no damage and the other party leaves, still call the police.
She could have returned when you left and called the police, claiming you left the place of accident. That would put you at fault by default.
Then she would sue you for her injuries. Heard stories like that, some people are shitty.
My mate’s car was hit by a scooter rider who broke a red light. There were no injuries or damage, so both parties agreed to let it go and drove off. The scooter rider then sued my mate. He won 110k NT.
Police can often find people even if there is not cctv at that specific intersection by looking at others in the area.
The point is that by then it does not matter what happened. The party that leaves the scene before the police arrives can be held liable for other party injuries.

I had similar incident where I was waiting to turn left. The guy behind me bumped into my car without any damage.
I called the police and it was annoying. But it was clearly established that he was at fault and we immediately settled after the report was done at the police station.
Drafted a document that we agree to settle without any further claims from both. The guy agreed to give me 1000NTD for my troubles.
