I'm sure one could just drive right through one of those arms. It's purpose is not to physically stop cars from being able to go, it's to discourage from going. Most people will see the flashing lights and stop, some may want to go, but they see the arm and don't want to scratch their car, then there's the idiot in a hurry drivers that will go right around other vehicles to try to beat the arm or go around it.
What are they suppose to do, have huge concrete walls that come up? People need to start using common sense instead of depending on others for their safety.
I really hope the rail road does not get into any kind of trouble, nor get forced to make any chances, because it's not even remotely their fault. According to the picture that setup looks like it goes beyond what a typical crossing is. They even have those top "towers" with the lights and everything. You can't miss it.
