We all have our opinions and here is mine: I completely disagree. I always want to have complete control over my car at all times. In my 58 years of driving I've never not been in control. And, roundabouts(traffic circles around here)would be the absolute last place I'd would ever use any kind of cruise control.
I use the normal CC only on highways.

completely agree - what sane driver would use cruise, adaptive or conventional on roads with traffic circles etc.

GSFRX350

The RX though doesn't have a ACC that is adaptive for bends, RBs or intersections.

I only use it for long trips with country roads/less cars. Set it to 3 bars and always keep my foot near the brake if the car gets too close or some bad drivers trying to merge/switch lanes too closely.

I really like it and have never had a problem with it not doing the right thing. It is kind of fun on 2 lane roads to allow it to brake as a car ahead of me slows down or stops. On long stretches of interstates that are not busy I have to watch it as I approach a car ahead of me. If I am not paying attention it will adjust the speed to what the slower car in front of me is doing. I may not notice it for a while and then rather than going 75 I might be going 70. I have learned to get in the left lane when approaching a car so that I don't begin slowing down.

Exactly the same with me, the slowing down is so gradual you don't notice.
When the car "sees" the one in front the display shows you, at that point I change lanes and keep a constant speed.

Is there a way to use the cruise control but without the adaptive feature ie automatically slowing for a vehicle in front of you.
I find it too sensitive even on the least sensitive setting but still want to use just regular cruise control

thanks

Press and hold the button an extra second or two. That engages conventional cruise with no radar.

In one of the last two episodes of Consumer Reports Talking Cars, they specifically mentioned there are numerous vehicles that are nearly out of control with the adaptive cruise by either being far too sensitive or not sensitive enough. There are no industry standards & every car appears to be different. They noticed that in a their test car driving in Connecticut stop & go traffic, even the shortest distance setting allows cars to dart in, from either left or right lanes, because the system doesn’t “see” the car darting in front. As far as I’m concerned, this equipment is still risky. It’s just like the self driving garbage that has killed people now. It’s not to be relied upon. Manufacturers must work together to reach a common standard like they did with seat belts & airbags.

I use it routinely in both of our cars with no issues. Don't use it if you don't trust it.

Don’t have it, don’t want it. Only the loaners had it & now I know how to disable it.

I trust it 100% because it can react much faster than I can especially in high speed driving with lots of traffic. I now cruise on highway always with this radar cruise control on even if it's bumper to bumper traffic. It's lot less stressful with it on. I love it.

If you have taken a "defensive driving course" the radar cruise will make you very nervous in stop and go driving. If a car is stopped in your lane you close way too fast and I can't keep my foot off the brake way before the RCC applies the brake. It does work and it is watching the road 24/7, but it makes me nervous. Wish it was there in the background so you could brake as well as accelerate without turning it off. It works but does not turn your Lexus into a self braking car because certain weather conditions will turn it off.

You have to try radar cruise -- it is amazing. Not perfect, but really a great feature if you need to spend more than 15 minutes on the freeway.

It's on the list... next time I'm on a country road somewhere - preferably with someone's company who knows what they're doing.
