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.
