Great... I can't wait to be hit by one of those on my motorcycle
I'd actually bet they're safer than some tweaked out dude on his 20th hour at the wheel.
Ok, elmo.
Same. Our government can't even figure out a way for us to trigger a green light so I'm not confident that any self-driving vehicle regulations will consider us either.
Heh, I got hit by that stupid thing today. Luckily the crosswalk button was right there, so I ran over and smacked it before the traffic signal cycled again.
I've heard of people doing this but my strategy is to just wait until it's safe and run the red light or go right and bang a uey.
I couldn't do that on my 49cc scooter 😅.
I've got a 1980 Honda XR500 as well, but it needs some work (and tires, badly) before it's roadworthy again.
Large neodymium magnet on the bottom will do it. Most are induction activated. They taught this in every motorcycle driving class I ever attended, along with the rules for legally running a red light.
That way you'll also automatically collect all sorts of valuable metal treasures along the route. For free!!
At least the screws won't collect in your tires! Lol
No, it won't. I invite you to get some large magnets and place them directly on the loop cuts in the street.
Well yeah, they have to move over the sensor loop. You can't just place it in the center. It's part of a process that happens as, you know, you pull up to the light. They are a little fancy.
Thanks dude, well aware they're looking for an AC signal. The added magnet isn't going to influence that, is my point.
Besides limited magnetic permeability of the magnet itself (the thing the loop is looking for), it's physically not big enough. What you really need is an amplified field distortion, e.g. a field coil which reads the sinusoidal signal being emanated by the sense coil, and loudly plays the inverse back so the sense coil thinks a giant block of steel slid over it.
This guy inductions.
I vaguely remember a dystopian book that described that exact thing as the protagonist thinking he was looking at an odd flag on the front of the truck until he realized what it was. Can't remember what the book was though 😔
