Put any relative or friend on it whom you might want or allow to drive the car. Your neighbour even. If it was parked somewhere and you broke a leg, who might drive it home for you? Make sure you get their consent.
It almost doesn't seem to matter about driving record either - my daughter wanted her boyfriend on her insurance - has was 19 at the time, had recently written off a nice BMW and had speeding tickets, and the premium went down! Yes it was all declared. She had a clean license.
