It does, but that rule takes the cake as the worst rule in the book, and not becasue it's confusing, just becasue it's completely dumb. Pg 201 says in you take damage based on the body of the vehicle you're in. It has nothing to do with the speed at which you were moving... So if you're in a bigger vehicle -standing still- you take more damage than a racing motorcycle?

Wait, I guess that's for vehicle crashes, but it's still a dumb rule.
As far as the Master-Blaster combo, I also have to figure a intuitive way to account for the fact that he's glued to the thing that is going to be taking fire. Simply declaring them to be separate targets doesn't seem right, and he's going to be a VR-ragdoll on the back most of the time.
There's so many out-of-the-box questions here. I want to be relatively conservative since a primary concern is that another GM (at GenCon specifically) will see things differently and club him with the nerf bat. Particularly since he'll be sitting next to me and not in front of me...
Does the drone defend when someone shoots at the rigger?
Does the rigger ever have to resist damage from attacks that pierce the drone armor?
