Absolutely, there was a time when fail to stops following a collision reached epidemic proportions and fierce penalties were introduced and enforced to stamp it out. It looks like priorities have changed but I'd be pursuing it hard with the police and raising a civil claim against the driver.
I've only had one situation where I needed the name and address of a driver from the police following a collision and they were happy to give me the info as I was an involved party. Again things may have changed but if they had I'd be raising a claim against 'driver of car XXNNYYY' and requesting disclosure of the keeper's details or I'd request them from DVLA.
