Sorry, that is not a feature. Give it some time and you will develop more confidence in both Highway Assist and Adaptive Cruise Control. They are both excellent.
Good idea. Most of my driving is in rush hour traffic. I feel safer when I'm controlling the speed of the car.
Watch the ACC when all of the traffic in front of you has stopped. My car will not stop until it thinks a collision is imminent then slams on the brakes. @borski disagrees but that's how my car works, and I think others have the same issue.
This 100%. I had a couple of opportunities where, while using ACC, my car approached stopped traffic. In neither instance was there a hint of slowing down. With the solid regenerative braking, it's rare that I have to use my brakes, but they got a workout in these situations.
We have three other cars with ACC, Mercedes and Ford, whose ACC work correctly. It's a flaw that Lucid needs to fix.
Does it behave any differently based on you ACC Distance setting?
Personally, I would like the Air to slow down faster. I can’t speak for your car, but when traffic comes to a sudden halt, mine will slow down and stop, but not before my blood pressure rises. In these situations I usually take over, unless I feel like living life dangerously. Seems to me that Lucid could easily improve the speed in which the car starts to brake with an OTA.
The Lucid doesn’t recognize vehicles that go from 70 down to, say, less and 30 or 20 mph in a rapid fashion ahead. It doesn’t matter if they are not stopped or less than 6 mph. The ACC just does not work well for rapidly changing speeds. However, my Leaf does. It is just a software tweak that needs doing.
To be clear, I don’t disagree that that’s what you’re experiencing! It’s just not what mine does.
In 2014 when Tesla first sold Autopilot, braking reaction to stationary vehicles were not that reliable from a high speed but much better with lower speed.
We've had the car for a few weeks and haven't tried Highway Assist yet. Posts like this really make me worry about using it.
