I'm thinking with the cost cap in place, some teams might do a bit more "road show" type promo events with their excess staff.
Then I was thinking, since lots of teams use v8 cars for these demos, why not encourage a 2022 update for these old designs?
Each manufacturer could do a modern tech Head/ignition/DI/exhaust update for their v8, and send them on the road as a "Technical Display" instead of just a loud party atmosphere... Better yet, the teams could travel together, and have a chassis dyno set up in front of the crowd.
I think it could be a thing!
