Adaptive cruise hidden benefit

No. How are you turning it off? Braking? What if conditions determine braking is the wrong course of action? Fumbling around for the button to turn it off when you should be taking evasive action?

If the object goes out of the radar cone of vision, it does lose sight, just as it will regain sight when the object returns to the radar cone of vision.

 

Awww, come on Rock!

It's only Taco Tuesday.

 

Because the cruise is accelerating or decelerating the vehicle does not mean I am not in control of it, I can and will do those things regardless. It is doing what I let it do and in every case I know what it is going to do and I allow it to do so.

 

I for one understand what you are stating where some just seem not too. Sometimes you can talk/write till ya blue in the face & your not gunna pernitrate. Lol.

 

Brake or gas the cruise does not preven that. If it's an emergency situation and you need throttle you have it, if you need brakes cruise is off. You hands have the steering wheel. There is no situation where cruise prevents you from the control you need. The only thing it prevents is coasting and that isn't an emergency response.

The radar sees more than in front of you it's the camera that determines if it's in front or in an adjacent lane. There is no situation where the radar will lose something in your direction of travel. If it's coming from the side then you should be managing that anyways.

 

Dude, idk. You sure do seem to have plenty of time to think about, much less discuss the merits of how and when to use adaptive cruise control, all while you're attempting to save the planet in the Tacoma vs Rivian thread?... One thing at a time, Elon.

 

You have never driven in slippery conditions.

Thanks for coming out.

 

LOL, grew up in Northern Minnesota. Learned to drive on dirt roads that were covered in snow for five months out of the year. Love in a snow state now. But thanks for playing

 

So much to respond to here, this has gotten spicy!

1. If you can’t see the vehicles ahead of you, you need to IMMEDIATELY begin slowing down to a speed at which the stopping distance does not exceed your vision. Understandably, there are times when your vision substantially decreases in such a short time that slowing down accordingly would result in an aggressive braking application that would itself be hazardous. In these somewhat rare situations, you should exercise best judgement when slowing down to balance the risk of rear ending traffic ahead of you with the risk of being rear ended yourself. TEMPORARY use of flashers in this case me be warranted.
2. I’m not super familiar with the specs and capabilities of the adaptive cruise or PCA systems but there is the possibility that it could be beneficial as the OP has claimed. (I’m not taking sides, just offering an example as the devil’s advocate since virtually everyone has already taken sides against him). Let’s say you are driving in reduced visibility at a speed that allows you to stop within your vision at a moderate rate or acceleration. I think most of us would agree that is A-OK. IF the adaptive cruise is able to “see” traffic further ahead and slows at a more gradual rate, I would agree that this is beneficial.
3. OP really should be aware of the risks posed by using cruise control in the rain. I do believe a lot of this risk is somewhat mitigated due to technology enhancements that others above have mentioned, and this may even be a good topic for a thread of its own. Personally, I do not use cruise in the rain.
4. I don’t think Firn’s use of adaptive cruise is entirely appropriate but he’s onto something in terms of risk mitigation and adding “layers of defense”, at least theoretically. I’d say y’all at least ought to let up on him just a bit. There are certain situations where his use of adaptive cruise CAN BE beneficial and not merely convenient. There are also situations, probably the majority depending on your driving patterns, where it is NOT. Generally speaking, more dynamic situations (downtown) require lower amounts of automation and less dynamic situations (back roads or rural interstate) are conducive to larger amounts of automation. Granted, the use of “automation” in no way should relive a driver of his responsibilities; it merely allows a shift of focus from tedious manual inputs to building situational awareness and managing the situation. The flip side to this coin is that automation in general can promote complacency and this risk should be balanced with its benefits.

 

Then you know if you brake you lose traction and control and if you accelerate you lose traction and control.

I hope.

 

I kinda dig the lane keeping assist on my honda civic. Albeit you have to grab the wheel when it panics its a nice feature on a low grade vehicle. Also the brake hold at lights is something i wash my taco had

 

Which wouldn't be an emergency then would it? Never had an emergency situation that was in such slipper conditions that zero input is possible and also required me to just coast IMMEDIATELY

 

I haven't thought of using cruise in fog, but it's an excellent idea.

One of the best things about the taco setup, is that to turn cruise off, it's on a little stick where your hand is anyways, so it's safe enough to use anytime. Though when it's icy, it wouldn't be worth turning off and on so many times

 

This person understands

 

I have, vehicle in front lost control hydroplaning and began doing pirouettes. Same would have happened to me if I had touched brake or gas. I was able to steer around it while coasting.

 

I once used cruise control in a blizzard. big mistake.

 

Dude, give it up. There are a whole two of you who drive like this.
Let me know if you are ever going to be in South Carolina and I will stay home that day.

 

That's why there's the big cancel button for cruise control. Hitting the brake to cancel is a noob move

 

I'm not the one who thinks cruise means you lose control of your vehicle or that you are no longer engaged with driving, how about you let ME know when you are up north.
