In order to be most effective it would need to be dynamic rather than a fixed on/off like rear brake lights. Stopping doesn't mean stopped. So perhaps a progressive light bar that starts lighting up at 20mph and adds a light for each 5mph drop until the whole bar is lit indicating a full stop. That would give pedestrians a sense of rate of deceleration.

The claim is we need more comprehensive regulation for brake/slow down lights.

They might need to check their assumptions. It might not feel like the brake is engaged but it's an expensive habit that causes unnecessary wear and tear. https://drivingmecrazyblog.com/2020/02/07/quit-riding-your-brakes/

It’s not engaged dude, the brake has play it in, and the brakes don’t engage the second you start depressing it. But the light is on. Called brake shadowing, do people not take driver training any more? Because maybe they would stop assuming brake light means brakes are engaged and they are riding them.

Quit reading blogs without understanding the basic premise of how brakes work first.

No, being in poverty is really bad here, but I just picked SK out as a close example, old folk becoming recluses who only interact with Fox News and people serving them is pretty specific to American and/or car-centric culture. Hell even car-centric parts of america have retirement communities where they all drive scooters or golf cars.

we can put the lights on the bottom of the mirror so you can see from that angle then

Well in any case I'm here and not there and when that happens there won't be money to go to some magical car free place. We have winter here and the groceries are 20 km away. There is no bus, no taxi and not even uber. Not that I would have the 60 bucks a ride would cost. Of course I would also lose my job which 60km away.

So deer slug to the brain will be the prescription.

And then they'd flash no matter which direction they'd turn?

So basically hazard lights all the time? Not sure if you still don't understand what this discussion is about and how I could make it any more clear.

It's not perfect but I think this is what people in this thread are fighting for. Which isn't stupid imo

Also known as the "fuck everyone not in a car"-setting

Well yes they will, but at least it's an option . Also a lot of vehicles have auto dimming now but they don't work well and don't last more than 6 years before the sensors get borked
