'Knight of the Drones' by Robert Foster and Gerald Sanford

A radio that transforms into a robot and an armoured car that drives itself break a criminal named Jackson out of the Santa Clara Penitentiary. Hearing of the escape, Devon is immediately concerned – as Jackson was the man who murdered Michael’s predecessor, Ken Franklyn. Sent to San Francisco to track down Jackson, Michael and K.I.T.T. find themselves reunited with their old friend Doctor Bonnie Barstow. In the course of their investigations they meet deadly robots, kung-fu fighting bodyguards and Margo Sheridan, an unscrupulous dealer who brokers everything from illegal arms to top-secret documents – and who is now planning to use her drone cars to steal millions of dollars from a Federal Reserve Bank…
