One of the local T owners has installed their NTSB / Ralph Nader approved Air Bags. It was a hit with the people attending the local street fair.
At car shows I usually put a sign on the windshield that says
"Yes it has and air bag"
"Yes it has a seat belt"
Yes it has speed control"
Then I put a bag like that attached to the firewall, and an old belt on the seat.
People laugh and say they see the air bag and seat belt and ask where the speed control is.
I then point to me and then the right lever.
It usually starts a conversation about how to drive a T
I am thinking about getting a T shirt with Speed Control on the front
