Based on a meme that @keganexe posted, I made a new archetype for their game In Extremis.
Edited to add: here's the text for screenreaders, modifications, etc.
Assign to Bone, Muscle, and Nerve as you wish: 4, 2, 1
Then cross each word out and rename them: Chassis, Body, and Transmission

Nice Ride: You can instantly identify the make and model of any vehicle. When you talk to someone about their vehicle, they’re automatically friendly to you unless you do something to hurt or anger them.
