    Because deceleration is not braking and conflating the two is extremely dangerous.

    Think for more than 2 seconds plz

      The issue is with regenerative braking and single pedal operation of EVs. Many vehicles today will essentially brake if you aren’t on the accelerator.

      Personally, I think it’s a gap in design/regulation. But not as simple as brake pedals.

    Standardised is a funny word, a car manufacturer doesn’t standardise. Laws and 3rd parties like ANCAP do.

    When they need to do it to sell it with certain safety requirements, they will.

    However, even if those happen, and car makers today start building them with that, it’ll take a decade or longer before you’ll start seeing them in majority on the road. So even if you lobby for it, expect time since I’d say less than half of all people buy new cars, so it’s not until the second hand market sees it will it be commonplace.

    Right now the second hand market is starting to see things like collision avoidance systems and they will often flash brake lights when emergency braking on behalf of the driver.

    Ok i’ll bite. Because why? How can you decelrate quickly enough to need to notify the driver behind you without braking?

      Engine or regenerative braking can very quickly slow down a vehicle but may not activate the brake lights depending on the manufacturer.

      Or crashing, I guess.

      EVs have regenerative braking, where when you let off the accelerator, it immediately starts slowing down, quickly. But the brake lights don’t come on. This would make driving behind EVs safer.

      Jake brakes in big trucks, but most of them do show brake lights now even though you just coast to activate them. Some drivers like to turn them off because it makes you look like a dangerous rookie in the mountains if your brake lights are on consistently while going downhill.

      Other than regen braking like everyone said (which really slows down a car almost effectively as brakes when set to the highest regen setting; look up “one pedal driving”), you can also slow down a car quite rapidly in a manual transmission if you skip a gear or two when downshifting. No brake lights come on when you do this, and honestly I think that they should.

      More accurately, if they added one single extra component like that, they would raise the MSRP by like $500. Because we live in capitalist hell. Therefore, it’s included in higher quality cars, and/or as an optional feature. Like most safety anything, they won’t automatically include it in anything unless they are literally forced to by law. And even then though sometimes not and say they did. And still up charge you for it. Isn’t capitalism fan-fucking-tastic?

        They take the worst of the three options. They don’t eat the dollar, they don’t put it in the base model for 500 dollars extra, they lock it behind the big wheels, sporty engine, and wood trim so only the rich people have safety features that aren’t absolutely required by law.

    This is probably country/region specific but my car (Tesla) illuminates the brake lights when it detects a certain level of deceleration. Also my work vehicles (Volvo V90 CrossCountry and XC60) do this. Finland/Sweden in my case. My car also flash the hazards when it detects hard braking and I’ve seen quite many euro cars do this. I agree that this should be standard.

      Activating the hazards when hard breaking is also just common practice to do manually (at least in western Europe)

    Not a car, but I’ve got a bicycle light that does this. Turns on when it’s dark and also when you brake. So definitely possible

    Some semi tractors have implemented brake lights that activate under exhaust braking, and its fucking annoying.

      Kinda worthless to put the blinker on after starting to turn, no? Also, probably doesn’t work so well when you need to change lanes or turn on curves.

      Blinkers should be blinking before you turn the wheel. I once drove as a passenger with a driver who only started blinking after he started his manoeuvres and those 40T trucks were hammering their horns for a good reason. Scary as hell experience, would not recommend.
