Does that mean that the 3000+ collisions and hundreds of deaths at railroad crossings in the US each year are due to vehicles that became disabled and stuck on the crossing?
That would mean that a "trapped vehicle" sensor could reduce the number of collisions and deaths significantly.
This is really where this discussion started.
