BUS accident again

Huraah , if this new braking system becomes a standard in vehicles, it will be slap to the face of LTOs, (copied) anti hazzard regulation. In sudden braking you are not to turn on your hazzard lights because you will not be able to signal the car behind you of your intended direction in case you have to change lanes to avoid the hazzard in front.

This proves two things.
1. Toyota safety engineers are convince brake lights alone are not adequate signal during emergency braking.

2. Toyota engineers does not believe losing the ability to signal during emergency braking is a critical reason to not use the hazzard lights.

I hope this innovation continues Im sure in the very near future, visibility sensors will be introduce that will automatically reduce your speed , turn on the headlights and turn on the hazzard lights.

On #2, I think that's stretching it. For one, the emergency brake flashes are temporary. It disables itself, presumably, when you let your foot off the brake pedal. 2nd, when you are doing obstruction-avoidance while hard-braking, I don't think that engaging the turn signal would be the first thing on your mind. In that regard, I think that flashing the hazard lights or the brake lights should provide sufficient warning to the vehicle behind to slow down or approach with caution.

The question now , are anti-hazzard lights advocate will buy vehicles equiped with this technology.?

That's a straw man fallacy. They are not buying a vehicle which has their hazard lights hardwired to flash ALL the time. On the contrary, they're getting a vehicle that uses a safety feature that is ONLY engaged under certain emergency conditions (ABS/EBA is triggered, a crash is detected and/or the airbags/SRS pretensioners are deployed, etc.).... which pretty much falls into the category of situations when these hazard flashers SHOULD operate.

The time gap from pressing that brake to a complete stop is not going to be instantaneous.
That hazzard light will be flashing for considerable time.

You can safely flip the turn signal with one finger unlike the hazzard light which will require your right hand off the steering wheel to reach the hazzard button.

Im not only talking whats available Im also talking future innovations thats going to be contrary to someones beliefs.

i have been driving for decades.
i have been in more potential fender-benders than i remember, that were linked to a sea of flashing hazard lights.
most of them involved a sense of disorientation and impending bump-car syndrome, at having so many moving cars with flashing hazard lights, in front of me.
whereas, it was rampant in many years past... thankfully, the practice has diminished.
whereas, before, it was a sea of blinkers, nowadays it is a more manageable one or two only...
... probably thanks to tsikot.com and other portals of friendly education.

one has to experience it, to understand it. my suspicion is, some folks have yet to experience it.
one or two blinking cars, is manageable; just stay away from them. i think, some post-ers here are refering to only one or two blinkers at a time, which, i believe, is totally different from...
a sea of blinkers from like-minded drivers, that causes one to want to step on the brakes and stop...

maybe, that technology of triggering hazard lights flash during emergency braking is to distinguish a normal braking from sudden braking caused by errmm a hazard on its path.

it will not activate for heavy rains or thick fog because the car behind already knows that, no need to warn them.

Stopping time for most light to light-medium vehicles from 100kph to 0 is around 5 or 6 seconds, give or take, depending on road conditions. The flashers would only stay for that long or maybe until you've let go of the brake pedal. But let's just say 10 seconds total. That's not considerable, IMO.

If you stomp on the brakes under emergency conditions, it won't take long to slow down to a more manageable speed (enough to release the brakes) or even come to a halt.

You can safely flip the turn signal with one finger unlike the hazzard light which will require your entire right hand to reach the hazzard button.

I agree on the 2nd one..... that's the main reason it's being integrated into the vehicle safety features so it's one less thing for drivers to worry about. However, the first one is highly debatable. The operative word is "emergency". The driver's first instinct is to stop the vehicle and/or swerve to avoid an obstacle or collision. Flipping on the turn signal stalk is typically not up there on the top list of things to do in an emergency.
