Insane risks are what give Vroom a reason to live, it seems. There's nothing that sparks his circuits like just barely out-running the expanding fireball of a Decepticon installation he just blew to smithereens. he made his name in the Asphalt Wars of Cybertron, and since that day has been pushing his endurance (and luck) with more and more dangerous missions. Sure, with his skill, he could probably achieve them with a lot less threat of injury or death... but where's the fun in that?
