Gates reacting to vehicles standing on them

[pavlukivan]

Normally gates only react to near people, but if they reacted to vehicles it would allow some stuff like:
1. if you have a rail crosswalk and randomly left a car there - trains will not hit it
2. It would really help in designs like this

If a stationary car is just "near" a track it won't get hit. Isn't it enough that a gate will stay lowered if the car is standing on it?

It is enough in most cases, but still - signals would help
