If you might be inclined to do a "hit and run" on a cyclist, then you should do so with a plain, ordinary car, like, say a white Toyota Camry:
However, the last thing you should be driving around potential witnesses is a rare British shit-box that wasn't even very popular in its hey-day, let alone this century, such as a white Triumph Dolomite:
Given that maybe 50 Australians actually bought a Dolomite in the 1970's (mostly in baby-shit yellow), and that of those 50 maybe 45 have rusted away to nothingness, that leaves Plod with 5 possible suspects. Four of those suspects have baby-shit yellow Dolomites, and one single person has a white one.
Hence, follow the investagory time-line:
Money quote: "Police are looking for a white Triumph Dolomite sedan"
