Enables the logistics grid for the Car when the Logistic System technology is researched. This gives the Car 20 logistics trash slots, same as the Tank and Spidertron, enabling it to interface with roboports. As a bonus, this also enables Remote Drive for the Car.

I literally changed two settings:

local car = data.raw["car"]["car"]
car.trash_inventory_size = 20
car.allow_remote_driving = true

If you want anything more sophisticated, let me know.
