Our insurance company have said that had the lady touched the micra's car, then he would have been at fault. As it stands, our insurance company will contact all witnesses, and will try and get his insurance company to take liability, although the likelihood of them agreeing is negligible.
And yes I have heard of stopping distances. Put yourself in my position and ask yourself if it is acceptable for this man to drive off from the scene of an accident, cause all this grief and not be penalised. That's my main problem with the way the law and insurance operates - that he had to have made contact to be deemed "liable".
