I live down in the San Francisco Bay Area and regularly go across the Golden Gate Bridge. While this is definitely nothing like where you live, there is a toll going over the bridge, and all others that cross the bay, and all of the toll plazas have cameras, good ones at that. A few years ago, the Golden Gate went fully electronic with bridge tolls, giving folks either the option of getting your equivalent of the EZ pass, or registering your license plate with an online account, both through the same company. Regardless of how fast I am going, the cameras always catch me, no matter the vehicle, and I always get charged. If you try and skip through without a pass or license plate account, you get slapped with a fine and it's mailed to you, without fail, long as your plate isn't blocked or obscured.
The cameras are getting damned good out here, you are very likely seeing the same upgraded cameras. I wouldn't plan on being able to skip out on tolls for much longer, such is the way of the future.
One thing I have heard of from a friend is he had a dealer trim around the license plate (on a car, not a bike), and it covered the bottom edge of the "E", so the camera likely thought it was an "F", and he never got charged. So, it is possible to fool the cameras, you just have to be creative.
