I work at a government facility with a security fence. There is an inductive loop embedded in the asphalt to automatically sense and open the gate for exiting vehicles. We recently hired several new employees one of whom competes in triathlons. He brought in his carbon fiber bike the other day for an after work training ride. As I was leaving the office I saw this gentlemen dragging his bike all over the loop trying to trigger the gate. I rode up on my 25 year old Miyata 610 and had no problem triggering the sensor. Sometimes we get ahead of ourselves with technology. (I showed the new employee where he could use his building key to open the gate.)
