Safety bollards; bollards are used by government agencies and private businesses to protect buildings, public spaces, and the people in them from car ramming, either accidental, intended, or intoxicated.
I notice that five new safety bollards have recently been installed at the state liquor store in Center Harbor across from Poggios Taphouse pavillion.
Where there's enough room, using large granite boulders or a strategically placed trash dumpster can be protective.
Here's a Center Harbor situation where their trash dumpster saved the day.

www.facebook.com/watch?v=2183666241954624 .... a full sized, red 2006 pickup truck with no one in it, and a manual transmission that was parked in the driveway next to the Center Harbor Fire Dept rolled backwards about 100-yards down the sloping grass Center Harbor town green, going airborne over a stone embankment wall, across two lane Route 25, and into the parking lot where it struck a trash dumpster and a parked truck. That dumpster and the parked truck is what stopped the run-a-way pickup truck. The red pickup truck was able to be driven away from the scene, but the delivery truck had to be towed because its radiator was smashed and all the coolant drained onto the ground.
Most important, no one was injured despite the possibilities.
