no valid license? then therefore, you are absolutely off the hook. just use it to your advantage: "driving without license" as for the claims of being "policeman", well, if he can't show an identification of being one, then he is phony...
another thing, where is he coming from, from your left or right? i know the place of the incident. marami nga dyang ganyang incidents. the way i see it, if he's coming from the rotund, on your left just before the collision then definitely, he swerved toward you. and yes, there's is still the benefit of the doubt that he intended to brake so that you would hit him- minsan may mga ganyang tao, para maka-kubra ng pera.
apparently, the culprit has some attitude problem- as you mentioned, he didn't have any DL's due to another road incident. it should explain something and the fact is, he shouldn't be driving at all.
any results from the police report?
