Is Highway Driving Assist 2.0 Worth It?

@Arlen
This looks great, but I doubt it’s legal in Germany. Authorities are very strict about modifications.

On well-marked highways, it maintains lanes well. On poorly marked roads or lane splits, it wobbles. Lane changes are slow and often fail. Definitely worth having, though—it’s much better than just cruise control.

Mostly positive experience. It struggles at night in heavy rain to find the lane, but even then, issues are rare.

I personally dislike HDA. On poorly marked roads, it picks the wrong lines, creating unsafe situations. I feel safer just turning it off. For long trips, I stick with ACC instead.

HDA2 works well, but it’s annoying when it adjusts to speed limits that traffic doesn’t follow. Also, it slows down abruptly when cars merge into your lane, especially on busy highways.

Will HDA2 get better with updates?

Legacy carmakers don’t usually offer major updates. What you buy is often what you get, apart from small bug fixes. Hopefully, Hyundai proves me wrong.

In perfect highway conditions, HDA2 can go several minutes without nagging for hands-on-wheel. It’s much smoother than HDA1 and handles curves better.

That’s impressive!

HDA works well on highways but struggles on poorly mapped roads. I switched to a Comma 3X, and it’s a huge improvement. It’s smoother, works everywhere, and doesn’t require hands on the wheel—just camera-based attention.

I hope Comma gets approved in Germany. It sounds fantastic.

HDA2 makes long trips and traffic much less stressful. I feel safer using it, especially in heavy traffic. It’s not perfect, but it’s a solid feature.

I’ve noticed my 2024 Ioniq 5 leans to the right a lot, so I often have to correct it. Also, the hand-on-wheel warning is inconsistent—it’s sometimes every 30 seconds, sometimes after 5 minutes.

Only the latest Ioniq 5 NE.V5 models have capacitive hand detection. Older models require torque input to detect hands on the wheel.

Ford’s BlueCruise is the best hands-free system I’ve seen. HDA2 is okay, but I wasn’t blown away.

The Mach-E isn’t an option for us, unfortunately.
