Looks like the LX 570 Auto braked right before the Camaro collided with the Rav4. If so I am really impressed. Just wanted to post it here.

Yep. It happened to me twice that PCS kicked in. Once in intersection, a pickup truck suddenly decided stop in green light and middle of the intersection. I was more worried the car behind me is going to hit me. Luckily the car stopped with inches of spare. Other time is off the highway ramp and vehicle in from lost direction and stopped try to decide which way to go.... both time PCS function worked very where, with big red "BREAK" flashing on HUD and high pitch beeping, then following by a throttle reduction and hard breaking, very impressive.

Or maybe the fact that the white LX570 on the left rides higher than most cars and the driver was able to see the white Camaro running the red light coming from the left and hit the brakes? Either way, it was impressive.

Question: . Does the PCS with emergency braking on the LX570 ABLE TO SEE TRAFFIC COMING AT THAT FAST SPEED AND STOP IN TIME? Is the PCS with emergency braking only "forward looking"? Anybody know?

Question: Does the rear brake lights light up during PCS emergency braking to warn people from behind?

PCS mesures distance and time to possible collision with the object in front of vehicle, yes, relative speed is the key. When PCS engaged, rear break lights will light up to warn the driver behind it. It works the same way in adaptive cruise situation, when LX detects front of vehicle and starting to slowing down from he set speed, the break light will emit to warn the driver(s) behind it.

This... I'm betting the LX driver was able to see the Camaro coming and stop in time as the generation of PCS in the LX570 does not support cross-traffic but rather collisions with vehicles traveling in the same direction (aka forward looking).

I thought so. Thanks for the confirmation. In order for the system to see that white Camaro coming from the left at that fast a speed , the system will have an extremely sophisticated AI to differentiate all three vectors of travel.

wow lucky for the motorcycle driver!

I dont believe PCS was available on lexus LX models until 2016. Someone else can correct me on this. Also, PCS wont activate on some models below something like 15 mph or something. It was driver reflexes!

Here is a link to the 2009 LX brochure that shows it: http://www.lexus.com/documents/broch...X-Brochure.pdf

thanks
so yes, PCS not available on LX until 2016 when it also added BSM and led headlights and all other gadgets to catch it up. Now its behind times again....

I don't understand your response. Per the brochure at the link I posted, PCS was optional on the LX by at least the 2009 model year. Did you mean to say that PCS was not standard until the 2016 model year?

How so?
