It’s best to think of Highway Assist as an assist, not a would-be robo taxi. Lane changes may come in the future, but for now it’s all about keeping you in the current lane and adjusting your speed to match the flow of traffic. And that’s it.
Personally, I greatly prefer the way it handles lane changes, as the automatic lane changing in my Tesla is terrible. Constantly have to override it, anyway. And once it disengages while you are overriding, you have to manually re-engage.
In the Lucid, just turn on your blinker, wait three blinks, and HA will give you back steering control. Make the lane change, and HA automatically re-engages once you’ve successfully steered into the center of the new lane. Smooth as silk.
I’ve found it does get confused on rare occasions with exit ramps, where it doesn’t quite know which lane you want when the lane splits. That’s pretty common to all these systems, as far as I can tell.
And the adaptive speed is better than any car I’ve driven. Never panics when a car cuts into the lane. Never brakes for no reason.
But it’s not an autonomous system, by any means. It’s meant to make longer drives less tiresome. And for that, I think it does very well.
Looking forward to seeing how it improves over time.
