Some people also put magnets in their boots[2].

Shame they only put the loop in one of two lanes, though...
It's probably already addressed: run the light. Check the regulations of your local jurisdiction, but it very likely that the light is treated as "broken", and you are allowed to proceed after verifying that the intersection is clear. Yes, I've tested this IRL.
If it's an intersection you deal with regularly, call the local DOT, tell them about it and they'll come recalibrate the sensor. Yup, tested that IRL, too. Buddy of mine said that in his case they met him at the intersection so they make sure his bike worked when they were done.
And, BTW, it's not a weight sensor but an induction loop. Meaning that turning the bike off and restarting it can trip the light. Something something electricity through the starter windings.
We've already seen how poorly designed test-data and training combinations can result neural nets that behave in a racist fashion. More broadly, neural nets have been enlisted in quests like find insurance risks or security risks and here they could really bad effects if they get veto power.
Uhh, or
(A) Back up, pull over your motorcycle, walk the crosswalk(s) as a pedestrian with a 'bike', get on motorcycle on the side of the road you want to go on, continue; or
(B) Make a right turn + U-turn as many times as needed to reach the desired turn? (3-way intersections can pose a problem, but the through road is most likely defaulting to green and if not you can pull over...)
If your municipality still treated either of the above as a 'serious traffic violation' yet still not springing for better sensors that likely exist for more mainstream compatibility then you're just living with idiots at that point (or they just don't like motorcycles :P)
The town where I grew up has a red light which only changes when a weight sensor is tripped. But weight sensors are expensive, and the approaching two-lane road only has a sensor in one lane. Worse, it's calibrated for cars, so motorcycles never trip it.
Yes, only. If you ride up late at night on a motorcycle, you have a choice between committing a serious traffic offense and waiting several hours for the light to change. No, this problem isn't ever going to be addressed.
I think it's damned reasonable to be scared of what we'll get when people hand authority to machines. Not for Terminator reasons, but for simple bureaucratic stupidity.
