In Europe they tend to use these nifty automatic barriers to allow public transportion through, but not regular autos. They are much more effective than gates or those tire slashing things, but it doesn't stop people from trying to circumvent them.
There is music to this video, so those of you at work may want to don headphones or wait until you go get home. The sound just adds to fun.
Stanford uses those barriers as well. Never seen a car impaled on one before, though.
