New neighbor

It looks like we have some new neighbors at the house across the street. It will be difficult for their friends and family to find them, since the street sign/stop sign was knocked clean out of the ground last night. I mention this in relationship to our new neighbor because their garage is showing some indications of a tramatic event as well as their car is showing a rather pole-shaped dent in it. There is also a remarkable lack of any skid marks, which is scary in its own right.

I've only seen one of the people who live there, a businessman by the looks of it. He drives an SUV, not the car that tried to defy the laws of matter. Should I go over and welcome our new neighbors and then nonchalantly ask about the half-raised crushed-in garage door? One thing I defintely know I'll be doing - parking off the street.

UPDATE: It turns out the teenage son crashed into the door this morning when he was moving cars around. There is still a mystery as to whether or not the sign post is the kids work.
