Its only a matter of time when one of these gimmicks causes a major accident, with a lawsuit to follow. Going to be interesting to watch.

This can be a hazard when trying to make a faster maneuver, but thankfully I didn't have that come up. I am hoping my next Lexus will have a way to permanently shut off all these nannies. A smart and alert driver can do more good on his/her own, vs. the chances of one of these nannies getting in the way and causing an accident.
Has any studied surfaced showing the rate or % of accidents caused by these? I am sure it does it's share of saving people who are not paying attention, but that aint me and I don't want to carry the burden of irresponsible driver's bad habits.

These technologies aren’t going away, they’ll get better.

all your naysaying doesn't negate the fact that the vast majority of accidents are caused by the DRIVER due to inattention/distraction, impairment (drink/drunks), or just bad driving/judgment. but i agree there will be lawsuits, just like bogus 'unintended acceleration' ones because drivers couldn't accept they hit the wrong pedal or got a floormat stuck.

i've no doubt that drivers such as yourself and mmarshall pay attention, don't drive crazy or under the influence, but you're the exception rather than the rule. only tech can save people from themselves.

My GS almost killed me once when I was switching lanes and it decided to slam on brakes in the middle of the road. I almost got t-boned that time. Another instance, my PCS actually caused an accident, 2 cars behind me collided. I will never in my life own another car with such stupid system ever. You can disable the PCS under your steering wheel and enjoy the car.

My X6M almost got me into an accident during an aggressive maneuver that I was trying to perform. I turn this crap off whenever I remember to do it.

Not necessarily, legal lawsuits might force manufacturers to abandon this nonsense alltogether.

I'll take that bet any day.

Does your radar cruise still work?

PCS, LKA, LDA, DRCC.. none of this replaces the driver, but rather assists. As for PCS, it cannot always prevent a collision but rather reduce or mitigate an impact. This example shows it is not fool proof. Can happen to any car with the technology.

I never use it here in NY, with so much traffic, it becomes pointless. But let me try it tomorrow, hopefully there won't be much traffic on the way to work. I'll get back to you.

A friend of mine had a LX570 and the PCS actually saved him from a bad accident. He said he didn’t have time to react to another car pulling out in front of him and it worked as advertised. It’s not perfect as has been discussed here but it does work and is not all negatives.

Yeah, I don't know that I would turn it off, even having had the false trigger

one false positive in how many miles? seems good to me. Might save your life another time, you never know.

We went through this in the other thread. Ultimately I think driving personal cars, even if they are self driving, is unsustainable. Hopefully we'll see a major reduction in car ownership in the decades to come, and this tech wont be even needed.

Except when it triggers for no apparent reason, it's no longer an assist but rather a hazard. Right now government is mandating all automakers to adopt this tech, but lets see what happens once law suits start rolling in.
