I might also mention that in some cities and towns, the turn lanes have under-road sensors. Bicycles aren’t heavy enough to trigger the sensor so an exception has been made to the law to allow a bicyclists to proceed through the light if it is red. Some laws specify that the cyclist must wait through one rotation of the light without getting the green, some say they must wait a certain length of time, and some allow them to treat a turn lane light like a stop sign. They are required to stop and look both ways before going through the light. In video #1 the cyclist did stop before finally going though the light. I can’t say what the law in that city is so I can’t say if he/she broke the law or not. Considering how well he/she was doing up until then I would consider that he/she made a legal turn.
It’s Dallas, and there is no such law in Texas. Motorcycles don’t always trip magnetic sensors either and that’s considered ‘too bad’ - so, nope, illegal here.
One other thing - the under-road sensors aren’t weight based. They’re magnetic. Attaching a small magnet to a motorcycle or bicycle will quickly solve the problem.
