Many automated garages ban motorcycles because they're unable to trigger the sensor.

  Or they make the barriers slightly shorter so that motorcycles can park for free.

    Which they do, recognizing the fact that if there are a few motorcycles parked in your lot, it makes the whole lot look cooler.

  Interestingly, I find that on my bicycle I can trigger the sensors in roads (which in the UK seem to be marked by a line of tar, where the sensor has been cut in and sealed up) by angling my front wheel directly along the line - my belief is that it gives a pretty strong signal because the rim of the wheel is a lot closer than a car would be even though they are a heavier chunk of metal (inverse square relationship). In fact my impression at one place I worked was that the sensor gave a stronger signal doing this as the barrier to get out went up quicker for me than it did for cars. I have extrapolated this belief and also believe that the sensors that detect vehicles before traffic lights also give a stronger signal when the rim is close by and the lights choose to turn my way quicker as they think I'm a bus. I can't really verify this though, because I only ever travel by bicycle. Anyway, I guess motorcycles are not quite as maneuverable as a bicycle, so would find it harder to trigger the sensors in this deliberate way.

    The trigger for lights in the states is electromagnetic. A lot of bikes don't produce enough to trigger so placing a magnet on the frame below the bike helps get you through the lights quicker.
