Slotcar Hobbyist Question!

Alright all you Opto22 gurus I have a fascinating question to pose to you. I’m looking at get involved in the slotcar hobby and I thought: “What does the opto22 world have that could be used to control a digital slotcar set?” Point of reference, I’m looking into Scalextric and their standard design allows for 6 cars max to be run on the same track (simple 2 slots). They also have electronic triggers which can activate lane changers at the hand controller through IR in the car and track. I’m sure this group would need more information but I’m curious to know what you all think could be achieved. Thanks.
