Or cheaply like 400 research points.
Currently I am forced to demolish Tech 1 stations while they could still be used for less feature-rich cars.
Example situation:
- I build Fit Body (Tech 1)
- I research Body Specialization and Sunroof
- I build the Tech 2 trio Fit Bodyframe, Roof and Doors
Not all my models have Sunroof. But I have to demolish the T1 Fit Body, or some models which should get Sun roof will be routed though it and won’t get the Sunroof.
Smart junctions are too far in the tree to help with this situation.
