From my experience, BMW has the best autonomous driving tech on the market. It's too bad so much of it is disabled in North America, but even then, they're ahead of most of their competitors. I will say, though, that the Lexus (2022 NX), and Mercedes (2023 EQS SUV) systems that I've tried aren't far behind.

This confirms my notion (and this is despite them not being able to use Traffic Jam Assistant due to the software bug that was fixed in software version 2022.11):

 

I had an EV6 and now have an i4.

DAPP and HDA2 are very similar but I prefer DAPP.

1. Lane changes are much faster in DAPP (and feel more confident)
2. DAPP only requires you to lightly touch the wheel (resistance based) rather than grip it. Gripping the wheel can often cause unintended steering input
3. DAPP re-engages steering assist automatically when it is lost or you change lanes, HDA2 requires you to hit a button
4. DAPP Hands free under 40mph is...nice!

The one thing better about HDA2 is lane follow assist. Loved having it on all the time even without turning on full steering + accel/decel assist.

Overall though, DAPP is better in my opinion. Keeps lanes well, no ping ponging. Some disengagements but rare.

 

Lane change is not autonomous in the DAPP as far as I know, but it is definitely in the Kia HDA2. I don't think I would use that often, but tested in the EV6 and it works well and reliable, but unlike me, the car is not taking chances and is very careful. It's the same with the parking function, EV6 has more options, you can park the car after exiting the car, not necessary to sit in the car, like it is in the BMW, but again, I park faster on my own than letting the car do the job.

 

DAPP has really shocked me and realize that I need it in all my vehicles moving forward. It's not perfect but pretty damn close for highway and bumper to bumper traffic.

 

I have it coming in my i4 and would never have considered it before reading these forums. I hope I have the same reaction you have!

 

I getting an EV in 2023 and the decision will be between the i4 and Ioniq 6. I tried a Kia EV6 and it just didn't click, but its Highway Driving Assist 2 (HDA2) was impressive, and is what led me to wait to see the Hyundai Ioniq 6 which will have HDA2 standard.

Has anyone compared Hyundai/Kia's HDA2 to the i4's Driving Assistance Professional Package? They seem similar on paper, but I'm just getting caught up to speed on the i4 now. If it's as good or better than HDA2 it will make my decision easy.

The main role of the car will be a 70 mile commute to LA, so driving assist is a big feature.

Yes, the Kia EV6 is the better car regarding the DAPP and the PAP. The Kia has a higher level of autonomy than the BMW. I am currently waiting for my i4 with PAP and DAP, but I know the differences since I tested an EV6 also, which my wife bought after evaluating some other cars, like the ID.4 and ID.5, the Kia Niro, Nissan Ariya, Mercedes EQA and EQB and she liked the EV6 most. I don't know the Hyundai or any other cars except the Leaf. The Leaf works pretty well also, but it loses the lane assist very often. It seems to have problems with seeing road edges and lane markers. The VW and the Ariya has serious bugs concerning the reading of road signs, VW blames this on the Swedish road signes, but that's pure BS, since I know in UK they also have issues, and other brands in have no issues in Sweden. The other cars were reliable, but the EV6 was definitely better than the BMW regarding the DAPP.

 

PAP yeah because of the summon from the key fob but I strongly disagree on HDA2 better than DAPP. It’s not a higher level of autonomy.

 

I feel like self parking from outside the car is impressive, but not something I'd use personally.

I'm more interested in knowing how the driving experiences compare. The EV6 has an impressive AR HUD system too, I should look into how that compares to the i4 too, although it's more a curiosity than a deal breaker.

 

I agree that the self parking is more of a party trick than it is for regular use, but you never know when you need it. I have been in situations where I would have used it if I had it, but sure, it's not going to be used every day. However, there are people with very narrow parking spaces, so the option is very useful. What I would also welcome in the i4, which is also available in the EV6, is the selection of parking direction. The i4 can only reverse in into a parking space. In the EV6, you can select to reverse in, or park with the nose in. There are situations when one is preferred over the other. Anyway, all the self parking is there mostly to impress on people, at least in my case, though if the i4 behaves better than the 330e I have now, I may as well use it, at least occasionally.

Regarding the HUD, we are not interested in that feature, so we chose not to have it in the EV6 or the i4, so that part is not going to be compared by me. My wife finds it disturbing, and I find it unnecessary, so when we borrowed a test car for a weekend of test driving, I looked up the setting and switched it off. The first time we test drove we had the HUD on, so my wife knew that she did not like it, and I owned a car before which had it, so I knew I did not need or want it when ordered the i4.

 

With the low nose of the i4, I'm starting to think I need to change my habit and always back in to keep from rubbing the nose...!

 

Excellent. Backing into a parking spot is the best way anyways (car is much more maneuverable due to the steering wheels in the back - like a fork lift).

(not ssh's comments
Regarding the EV5 being able to parallel park nose first is kind of silly. Even when a human like me does that, its a bit of a stupid effort effort - backing into the spot is faster).
Lastly, parking the car when out of the car? are you kidding me - why would you want to do that other than "look me do this". Nobody stops the car in the middle of the road, gets out of the car, steps on the curb presses the car key and the car parks. The i4 with PAP can do this, BMW just doesnt think its a good idea to get out of the car to park it or having a human around to abort parking when needed. It is truly autonomous parking, no feet or hands required.

Or just be like this:

Man, I know I've been one of the loudest proponents for DAPP doing more like my current Tesla's Auto Pilot, (just ask ssh!) but I would never use any of it for city driving. I only want hands free or any automation when I'm on the freeway and in the far left lane. Way too much going on in city driving to not have full control.

 

I continue to be extremely concerned about the faith some people put into these Driver Assistance systems. They are NOT driving automation systems, but the rhetoric--especially from Tesla and Musk--have people believing that they are or shortly will be. Not so. And trusting them at that level is putting faith in unsupportable promises. BEWARE! These are life critical systems.
