When it comes down to a collision situation between a Frigate and a SOL, the Frigate gets to choose who goes first.
Why?
SOLs have every combat advantage over a Frigate, except maneuverability. Allowing the Frigate to choose gives them another slight maneuverability advantage in that limited situation. They need all the help they can get.

When the ships are that close, who goes first can make the difference between a collision and a nasty point blank raking shot.
