NSW Police said the two vehicles continued to Ultimo where they stopped at traffic lights opposite the Broadway Shopping Centre, which was packed with lunch time shoppers.

Police allege the driver of the Mercedes deliberately reversed and hit the Yamaha motorcycle, pushing it backwards and forcing the 30-year-old rider to jump off to avoid being run down.
