A Galactic Security Agent is trained to be expertly proficient in handling all kinds of vehicles. From sophisticated fighter ships to your average commuter speeder there's nothing they can't turn into an efficient pursuit vehicle. However, if given the choice, I don't think Missile Mouse would have picked the Speeder Ball SB5 as a get away vehicle. It's handling is poor, acceleration rivals that of a Gorgonian sand slug, and it's noisy. But when you're in a pinch some things have to suffice.
