Exactly!

I have owned two all-electric cars, and really enjoyed the one pedal driving...and although PDA is not that, it is even more helpful in avoiding a rear-ender when one's attention is not on the road ahead.

 

It may be mostly one pedal but Tesla's "one pedal driving" is quite different bird. It came as early Teslas had rather primitive system with brake pedal for friction brakes only. People then got this wrong idea to avoid brake pedal at all costs to save range, and so no coasting and tiresome attempts to balance vehicle speed with one pedal.
Prius and later TMC hybrids had much more sophisticated braking system invoking regenerative braking and then hydraulic backup and so didn't need all this. Coasting is actually good for fuel economy. Regenerative braking only saves fraction of energy, it's better to keep car going by inertia while you can.

 

I’m still getting used to my new RX, and I’ve been experimenting with the PDA system. Does anyone know if it is OK to step on the gas when the car is trying to slow down? Is that equivalent to stepping on the brake and gas pedal at the same time? Or does it automatically release the break the second that you step on the gas?

 

I'm still getting used to this as well and feel it brakes a bit too early when approaching a stop. I have found that I can feather the accelerator a bit to so that I'm not crawling to a stop.

Does anyone know if there is an adjustment to the sensitivity similar to the Adaptive Cruise Control distance setting?

 

I have that enabled on my NX. With PDA, it seems to help apply the brakes for you but when the vehicle ahead starts driving it will disengage the PDA. Pretty neat feature even it stop and go traffic.

 

Yeah, I agree it stops too early for my liking, I adjusted the ACC distance to the shortest distance thinking that might be the same distance setting as the PDA. It may have reduced it, I’m not sure, I’ll have to do a little more testing with it.

I have also feathered the gas as well. I hoping that isn’t a problem for the car (seems to handle it fine though).

 

My PDA is turned on but it only seems to work intermittently. Can any offer suggestions?

 

it seems to work in slowing my vehicle down once traffic slows down. Not sure what you mean by intermittently?

 

Websurfer - Even though I have PDA turned on all the time, some days it works just like it should but on other days it doesn't do anything.

 

do you get any sort of warning that your sensors aren’t clean? I know that happens in my BMW. I haven’t experienced it in the RX yet.

 

For mines, a car would appear on the dash if it's helping me brake for example.

 

You probably just not close enough to the car in front of you for for proactive assist to start breaking for you, or in your settings it set to something like low or minimum or things like that. The appearance of a car on your dash is only means that your car sees the car in front of you and you are getting close to it, it does not mean that your car starts to react to it at that moment.

 

I know of no setting that changes or adjusts, how the proactive driving assist slows down. Someone please point one out to me.

 

Adjustment of the vehicle-to-vehicle distance is on the steering wheel. It should affect slow down even if indirectly.

 

I’ve tried it. Does not seem to affect it.
