PDA (Proactive Driving Assist) may be better than I thought

I've also got it enabled and haven't minded it so much. The roads around here are mostly flat and straight, but there's one stretch that I drive occasionally that has two tight turns at the county line(the larger county roads were offset by 3/4 mile, so there's a correction at the line). The correction was built when average speeds were closer to 50-55mph, but the typical speed on the road is now 60-65. The PDA lets me just leave the cruise control alone as I approach the curves.

Reading your post, I've also realized it's going to be nice to have the next time I go over the Rockies. The last few times I did it, I was in my old 2010 Prius. There were always a few times going downhill that I would be more focused on the road and traffic than the speedometer. I'd be coming downhill and approaching a turn and look down and realize I was going 90+mph. Once or twice I looked down and was in triple digits. It will be nice having a smarter cruise control helping out when I'm getting task saturated.

 

I don't know if mine has changed, but the last time I checked, it follows curves until it decides not to. It can be a bit unnerving, when you're going around a curve and it suddenly disengages. Of course I know that I'm supposed to be ready to take over control all the time, but if it lets go in a curve at the wrong second, there's a chance of hitting oncoming traffic.

 

My son uses the Blue Cruise on his new truck and he said he can drive for hours on the freeway without ever touching the steering wheel. But he has navigation and I think it uses the built in maps in addition to the cameras.

I tried it on our road trip and didn't like it at all. It tried to veer to right when driving by off ramps. IMO, if you're driving 80 mph on the freeway, you should be in control at all times.

 

But arent you talking about normal DRCC with LTA? I activated in my options that Speed should be decreased during DRCC in curves but thats kinda unrelated to PDA. PDA seems more relevant when DRCC is not active.

I had moments too though where it tries to catapult me out of orbit, despite decreasing speed.

 

PDA is actually deactivated when DRCC is active. So you get less steering assist. But the DRCC has its own curve monitoring function for speed.

 

Who knows what all those acronyms mean?

 

I just got back from a 2000 km trip, and the various driving assistants are a godsend. I'm not nearly so tired after a day of driving. One potential hazard is falling asleep at the wheel. It's supposed to detect closed eyes, but that has never worked properly.
