I feel like there is a bit of ethical hysteresis here. If you have buttons that are designed to be placebo from the start, I find that unethical. If you have buttons that work, but have to be disabled due to a change in plans, that strikes me as less problematic (but they should still eventually be removed). So, how you get there matters.

Wouldn't a countdown timer solve the need for those buttons?

If people's behavior can be modified simply by giving them the perception of their input mattering then I would expect the coming AI interfaces/assistants and goal oriented concierge services to pick up on this and leverage it, which could get pretty creepy depending on the goals involved. Advertisement disguised as meaningful interaction.

Earlier quoted context omitted.

I'm sure I'm in the minority but I don't even think it is that. If the button at each intersection prevents one accident (hospital or even death) then it is worth it. So people got tricked to be safer? Oh, the humanity. People who are going to cross anyway still will.

What if it prevents one accident today, but causes two accidents tomorrow?

What if eating cereal for breakfast is healthy today but causes two accidents tomorrow?

I notice a lot in London that there are a bunch of pedestrian lights in areas witha steady flow of traffic that will only work if the button has been pressed, yet every single day I see people, often the same people, stand there until someone else presses the button.

Part of me wonders if there's almost an aspect of not wanting to cause offense involved. If you're the person who presses the button, you're responsible for the ire of whatever drivers you delay, so you'll either wait for an gap to run across the road or someone else'll press the button and absolve you.

This makes me so annoyed. I much prefer ones without buttons because I don't have to mess with it; when there is a button, I assume I have to go over and press it, but it sounds like in some cases I don't (for a while now I've suspected them to be pointless). But there's no way to tell the difference so I still have to everywhere.

Londoner here - I personally don't press the button if it's only me and the road is not busy since the time I would save would be lost over all the people I would make stop just for me.

I've seen many people not press the buttons thinking it's just there as a placebo, it's mostly tourists though as it's common knowledge amongst Londoners that the button signals the traffic operating system that a pedestrian would like to cross.

I'm fairly certain most, if not all, the lights in my area are automatic, however pressing the button rapidly causes the "wait" message to repeat as fast as you press it, which is a good way to pass the time while waiting.

More on topic, I wonder if people who jaywalk don't press buttons, or people who press buttons don't jaywalk? Seems like people who are already not going to jaywalk are more predisposed to button presses, but will not cross against the light even if they don't press the button.

I work in New York, but I go to Seattle periodically because that's where my company's headquarters is. How people treat the buttons is wildly different between those two cities. I hardly ever see anyone press the cross button in NY, since the convention is to wait for there to be no cars and then cross (and not bother with the button). In Seattle, I've seen people wait patiently at a cross walk even though there's n…

I believe jaywalking is illegal, and enforced in Seattle.

When I'm in the UK I will normally not press the pedestrian button (unless its the type of pedestrian only crossing which only activate with the button, not on traffic lights on a junction) . But when I'm in the US, or a different country with jaywalking laws, I will stick to the rules much more rigidly.

I also really enjoy the first time crossing a road when I get back, the taste of freedom!
