Do you trust the adaptive cruise control?

Ha, Ha! I found the system so flawed & intrusive that I will never own it! It scared the living ***** out of me more than once & I can’t have that. It’s great for stop & go traffic, but certainly NOT open highway with gentle curves. Lexus has tons of work to do on this awful system.
Has anyone noticed their rear cross traffic alert doesn’t pick up pedestrians & often times vehicles, until they are right behind your bumper? One dealer told me the system is working fine, but it almost never works at the grocery store parking lots. I thought that’s what that stupid system was for!!

The rear cross traffic alert on mine is a little too sensitive - it sees cars a lane away. It has, however, saved me from backing into a car that was backing out of a parking space behind me.

You are talking about the adaptive cruise control aren't you? Set the speed and the car will keep the set speed/distance from the vehicle in front?
If so I find mine fantastic, works faultlessly, I spend a lot of time on freeway type roads and the system has never failed to slow correctly and accelerate back to the set speed seamlessly. I will say going over a sharp rise will have the car go over-speed for a few seconds but quickly brings it back down.
Why is it "intrusive", it's meant to take control so obviously it intrudes on your driving?
"Gentle curves" - the issue there? Obviously it works to a set speed so will try to keep that speed around the curve.

I don’t think your understanding what I’m trying to say. The radar cruise fails when you approach a slow moving 18 wheeler in another lane when it appears that your are going to cross its path. The system is dumb & cant tell the vehicle is in another lane on a curve. It’s a huge risk & waste of money in my opinion. I’m sure it works good on flat land & bumper to bumper traffic. Intrusive to me means it begins interfering with my normally safe driving & puts the vehicle into an unnatural deceleration that could cause the car to skid or become a hazard to other cars around me.

Damned if you do (the tech is not very good) and damned if you don't (everyone else offers it).

I fully understand what you are saying but mine works flawlessly in the situation you described! I have never had my cruise control sense a car or large vehicle in the other lane on any type of road from interstate to local highways.

I have a question about "stop and go". When you apply the brake, the RCC is turned off? Therefore the stop and go does not work.....RCC is off. How do you keep it working? When the freeway turns into a parking lot, do you let the RCC bring you to a stop? And then the stop and go will work? Or am I missing something? When I see brake lights, my normal instinct is to get on the brake and that turns the RCC off.
If the RCC sees something that is not in your lane, the fastest way to override it is to tap the brake??? But if it is braking, will tapping the brake turn if off? Then you would have to go to the stalk??

Driving too close to the vehicle ahead is a massive problem, here in Australia it's the most common crash that happens, nose to tail and most likely is common in the US. The system at "3 bars" is driving at the appropriate distance to stop the car if need be, a safe driving distance for most situations. I know you'd like to closer so that's when you can adjust it, but put it on "1 bar" and it's quite concerning how close the vehicles are and I start to think "will it stop in time" for my liking.
Which is why I never use the radar CC. Only the "regular" CC that I can control.

OK, that makes sense...... after braking to a stop you pust the stalk up and re-engage the RCC and the stop and go will work. Of course the Forward Emergancy Braking SHOULD keep you from rear ending somebody in stop and go traffic. I've got to play with this some more.

The adaptive cruise should NOT allow any rear ending if it's operating properly. I typically don't use it though in stop and go - only on open roads where it works pretty flawlessly.

ACC enables safer driving by monitoring other vehicles and objects on the road, adaptive cruise control enables a safe and comfortable driving experience. It does so by helping the driver keep a steady vehicle speed at a given moment. The car will brake and accelerate on its own, while maintaining a safe distance from the vehicle in front.Intelligent cruise control systems rely on the vehicle’s connectivity to obtain early warnings and adjust speed accordingly. The result is a safer and more comfortable journey for the driver and passengers. Also helps with driving strategy choices, such as selecting a safe speed for the upcoming bend. Helps with driving strategy choices at roundabouts and junctions, without cruise control cancellation (selecting a safe speed).
