TSS 2.0 LTA with mm-radar adaptive cruise control impressions

I use Dynamic Radar Cruise Control frequently. I don't have LTA. Cruise failed me once but it was in heavy rain which is a situation where it's not recommended to be used so that was on me. TSS isn't autopilot so you do need to be on your toes.
Question: You don't mention the weather (rain, snow, severe clear) or your cruise control distance setting (1,2,3 bars).

 

I use the Dynamic Cruise Control very frequently. It’s very effective (1000 miles a week for my work commute—I’ve used it for 80%+ of those miles over a five month period). I adjust the “distance bars” as needed in any particular situation. Also, it disengages automatically and quickly if traction is not appropriate (tested it on a deserted stretch of road). Regular cruise control does not.

The LTA, however, is not especially useful. After about 500 miles (over several days of driving in various situations) I gave up.

 

comma – introducing comma three

 

Is it even possible to determine comma's long term performance is?

Teslas crashing while Autopilot is on make news, and the NHSTA is requesting incident rates from other car manufacturers involving their advanced driver aids. If someone gets in a crash with it active, how many 'forget' to mention it was in use? How many crash investigators know to even look for it?

 

OP, TSS is not autopilot. I cannot/does not look at other lanes of traffic for DRCC, only directly in front of the car. If a vehicle is merging or even exiting, you will want to override the system to make appropriate adjustments. I agree that the LTA also ping-pongs a bit too much - it is actually smoother in my Rav4 Prime, for whatever reason.
The DRCC is best used when there are few on/off ramps. We still find that it is very helpful on longer drives and relieves the stress of constant speed/distance adjusting for other drivers. I've been finding DRCC is more helpful for stress relief than LTA - much of the time I'm "fighting" LTA to drive smoothly in my lane.
Hopefully the next system gets better. I'm not brave enough to take on the liability that comma ai thingy would introduce!

 

TSS and Autopilot are both advanced driver aids. Pretty sure every major car manufacturer now offers such. What each suite can handle on the road is going to vary. Autopilot looks into side lanes. Others may not. Best to read the manual before using them.

 

I use the LTA on my 2021 Prime sometimes. But it tends to wiggle in the lane frequently. Makes me wonder if I might get pulled over for drunk driving and have to explain it.

 

I've been driving a Leaf that has ProPilot since 2019. It's one the reasons I switched to the Leaf. Even though I don't have experience with TSS 2.0 LTA, I can tell that Nissan's LTA is better from what @Gokhan is describing. I can't wait to try out Ford's BlueCruise, Kia/Hyundai Highway Driving Assist 2, and ProPilot 2.0.
