Well full credit to Surrey Police, just phoned me and supplied all the details. I've always been impressed with my dealings with them and Surrey Heath Council.
They have provided the drivers name, contact number and full insurance details. Apparently he was a local Indian lad, living at home. Police called at his parents, who then called him. His story is that his 'tyre blew' - This is not something myself, the Police Officers or the witness will agree with

He panicked and drove off to the Co-Op is his version, bought some ciggys

He handed himself into the Police Station, passed breath test, no issues there. He also said he wants to avoid insurance, as he know's 'local trade people'

But as the officer said, this is my call not his. I allowed police to supply the lad with my contact email, I've told them he needs to supply in writing his version of events and why/how not to use insurance.
I want the little sh!t to grovel and explain his actions. Anyone could have been hurt, he just drove off.

I plan to still use insurance, should teach him a lesson.
