@GirishH be advised that weight is not used to change trafic lights. Most lights unless recently updated, or older ones modified/supplemented use electro induction to cause a change. Often that system is faulty or out of adjustment. The problem arises for bikes because you are not in the area where the bike will be detected since most are riding well to the side of the field to cause the interruption of it. Enough conductive material (generally the rims not the frame) is all it takes so carbon fiber only rims might be the new problem. Very small rims can also cause issues. At night when commuting without traffic I ride in the center of the lane to better ensure the systems work, but it doesn't always. When I approach the light seeing it already red (and no cars behind me), I slow down and do a loop overel the grid, l and voilà the light changes unless it was still being timed from previous vehicles passing in the crossing roadway.
Even motorcyles can experience problems if the system is misadjusted or faulty (if fully inoperable no vehicle will activate it). We have no dead red law allowing you to pass through a faulty traffic light without breaking traffic so I'm taking a risk at one light which is timed for day traffic and does not change for minutes at a time (you need to make a right hand turn amd then make a U-turn (again when legal to do so and proceed onward). Luckily, it has a pedestrian crossing circuit so I hit the button and it does change quicker than waiting for the traffic only cycle.
Lights now include cameras, infrared, motion detection, and algorithm control systems based on traffic flow. A new system is being incorporated specifically based on automated driving vehicle flow and not on vehicles driven by people.
I have been stopped at gun point by police for armed robbery at night while on a bicycle even though the perp was not on a bike. Police stopped me and just said hands up, do not move! I was wearing a hooded sweatshirt (temps were in the 30s F) with hood closed over my entire face except eyes due to wind chill. I rode w/o lights or reflectors (no law s at the time requiring them; I raced at the time) could cycle around 30mph without problem in my ~5 mile. I was being followed by police w/o knowing, and upon approaching a stop sign I did a quick track stand and the car behind me got right up on my butt which greatly irritated me; and continued to do so after the intersection (speed limit was either 25 or 30mph (cannot remember, but was residential about 1/2 mile from my house). Upon approaching the next stop sign I merely slowed a little looking well in advance for approaching vehicle lights and seeing none I just put on the afterburners and flew through the stop and gave the 1 finger salute to the vehicle behind as I pulled away. Blue lights immediately came on and I was given the order to stop. Police had not even been given a description yet except to look for a fleeing suspect. I guess flying on a bike at high speed at night only a mile from the crime scene applied to me. They yet me at gun point until back up arrived. Handcuffed me, shoved me into the car and searched searched my backpack. At that point I heard on the radio while in the car the perp's description and through insane coincidence I actually somewhat fit it. I was an active military member at the time returning home from the base.
They drove me to the scene of the crime which happened to be the local McDonalds restaurant. They literally did a "drive-thru" identification with the clerk hanging out of the little window and saying (thankfully!) that I was not the assailant. Cops drove me back to where my bike and pack and other cruiser sat roadside. They let me out, uncuffed me and said nothing but you can go. No sorty or anything.
Lessons learned: none! Anger increased towards police as this was the second time I was at gun point (on foot that time) for doing nothing wrong. My only take was that I was thankful that I was not considered to be a "person of color" nor did I make any foolish actions or speech while having multiple guns pounted at me lest I not be able to relate this factual story.
I again ran into police ready to blow me away while turning my car into a gas station about 1 and a half years ago after multiple cop vehicles were again tailing me late at night w/o my knowdge looking for a shotgun toting madman driving (what I was told) the same car as mine (same tag?). Again I did as directed and retained my life for the next encounter. No one believed me until I actually had another police encounter with someone in the vehicle with me while driving a work vehicle (and that dumbass was carrying a firearm w/o my knowledge as we went do a job at a public school! He deserved to be shot; no one discovered his stupidity thankfully).
Thus my user name of "Criminal"; not because I am one, but because the action I have been exposed to were just that. Now I wish they had just shot me dead and saved me decades of paranoia!
