Driving to work in my prime premium, turned off the highway onto the ramp to merge onto the secondary road. I'm looking left to merge into the traffic, then when I look back ahead of me, I see the idiot in front of me had STOPPED DEAD IN THE ROAD. I'm going about 50+ mph, about 100-200ft behind him/her. Applying full braking, I luckily managed to steer around and luckily nothing was there in the road to my left. I doubt I could have safely stopped without hitting him/her. So this whole time, the emergency braking /alert did absolutely nothing. What's the deal?
if you have you're foot hard on the accelerator it won't engage.. it assumes you're in the process of taking evasive maneuvers so it won't cut power and potentially put you in a bad spot. likewise if you turn hard, etc. it also won't engage. that's a catch 22... you're accelerating hard to merge and an idiot stops. that's the main dead zone in the system operation.
In the UK it only works below 30 or 40 mph. It isn’t all speed. If cruise was engaged then that might have braked. iPhone ?
On my highlander (and I'm sure I've seen the same on the prime) even if you are accelerating, the display will flash a bright BRAKE. It doesn't take any action but it still flashes and beeps. It's pretty easy to activate. If you are speeding-up to pass someone in front of you and are late (according to it and my wife) fully moving over to the left lane, bingo...You get scolded... Check the owners manual... Page 369 starts a whole description of how to enable/disable and when the system might not activate. For almost all the cases, even if it doesn't activate, it should flash the BRAKE warning.
At 50 mph, it should be able stop in 90-ish feet, unless the tires are worn or the road conditions are compromised precipitation.
If people would RTFM, that would eliminate 1\2 of the topics. If we then removed all of the Facebook-type posts, we would have a manageable and informative database. Why would we want to do that?
