@baukepost The green screen you mention is a Head Up Display (HUD), which usually gives extra informations for the driver, in an augmented reality (AR) fashion. So that mean, if you remove it, that these info must be somewhere else, so on the dashboard.
I would go for a big screen on the middle of it and some buttons on the sides. I think it’s a great idea to keep it a little bit old school as well. For the screen I was thinking of something like this display:
The tricky part would be to make it look a bit less futuristic perhaps ?
Since it reminds me of a motorcycle, you need to also think ergonomic: both hands of the driver are needed for driving, and the driver should avoid having to play with all the buttons while driving 🙂 Safety first!
