I saw that at the show. Not that impressive in person. My buddy said he knew a couple guys with them and they don't work that well. It is also like a wave that moves fast. A still picture may catch it in between ocsillations. Therefore be ineffective. We have what we call the fast lane here. There isn't a gate. The lines in the ground, same as stoplights, actually pick up the large mass of metal your vehicle has. That's why you are always waiting at stop lights. Bikes don't have enough metal in them. If you go around or quickly over these than they don't detect you. I do it all the time.
