"Stabilizers, AI whirly gigs-- I would explain this seriously if I thought you could follow along," Tony teased, doing up the chinstrap with a snort. Not his best look, but it would keep his mind intact should they get into an accident. Steve might just bounce a few times and pick himself up but Tony absolutely would not.

When he was seated behind Steve, arm around his waist, he couldn't help but laugh.

"Enjoy the ride, Cap." He wasn't explaining it but he did hope that Steve got it so he could laugh at the others discomfort.
