How obtrusive is safe and smart?

[Bullitt]

It's worth noting that the AEB in the Mustang has 3 sensitivity settings and if I remember correctly, the Low sensitivity I believe was described as only intervening when a crash is already certain, but will lessen it's severity. So I believe the sensitivity can be set low enough that it'll still let you hit the person in front of you. If this tech was forced upon me I'd use that setting and hope it never mistook some imaginary object for a "certain crash".

I'd also like to know if it returns control of the braking system back to the driver if he then gets on the brakes sufficiently hard, or if it is generally intended to drive your car straight into anti-lock and leave it there. And I wonder how well it would work with brake pads that have significantly higher mu, initial bite, and temperature resistance than typical OE (street) pads.


On edit, I would expect ACC to be able to cope with more than just minor accelerations and decelerations sensed in the car ahead, and I can't think of any reason why ACC would not use the same sensors as AEB. It would make sense for ACC to be able to hand control over to AEB if the situation suddenly warranted that much braking.

Yes, it seems to have returned control to me immediately once I started pressing on the brake.

To your second point, you are correct ACC will brake and accelerate with the flow of traffic. So when I say "gentle" I just mean if traffic starts slowing up the car does too- it only dynamites the brakes if it HAS to (so far). I would expect that it would accelerate harder in an auto car, but mine is a 6 speed and so if traffic slows to 50 mph it can only accelerate so hard without me having to shift.

Whoa - you have ACC and collision detection/prevention in a manual car?

How does it prevent you from stalling during an emergency brake? Lugging when traffic slows to 20 on the highway?

Yup, I sure do. To answer your questions simply it doesn't as far as I can tell. If I'm cruising at 80 and traffic slows to under 50 or so I would need to shift and re-engage ACC.
I don't mind this, it just comes with the territory of a MT...but ACC would be even more convenient in an auto for sure.

That's interesting. I guess that's one way to make sure you're paying attention even with it engaged! Do you also have the lane assist?

Yes, it all comes as a package with the S&S system. The lane assist is neat...not something I would have paid for as a stand alone system, or that I can about a whole lot. It would probably help some distracted drivers provided they don't use it as a crutch but for those of us that pay attention it's not particularly needed. It's also really easy to turn off- a single button push on the end of the turn signal. You can also adjust what it does in the menu (vibrate steering wheel on/off, nudge you back in the lane on/off, make a noise when drifting on/off).

Interesting that one poster thought that these fancy nannies might make us pay attention MORE, ie anticipating what they might do. :lol:

I think that a deer suddenly leaping into your path at night would be a perfect test of the AEB system. The world's most attentive driver cannot react fast enough. Only seeing the yellow deer roadsign, and slowing down accordingly will help you in this situation.

I like the “nannies” as long as they can be turned off or nearly-turned off when I wish to do so. However, I don’t believe they should be an excuse for a person to not pay attention while behind the wheel. On long trips of turnpike/highway driving they are, IMO, incredibly desirable.

For people with 2018 and have the safe and smart package how often/much do the systems (lane assist and auto braking) come on? Say you are in traffic and want to cut over and the systems think there is not enough room will it still allow you to move over or will they kick in and keep you in your lane? A buddy on mine has a 2016 Cadillac and it has the BLIS and lane assist and so on, he was telling me he had to take the car back to the dealer to have them shut those systems off because the lane assist would keep him from changing lanes if the system thought there wasn't enough room regardless if there was. I sometimes find myself cutting my way through LA traffic and don't want the system to stop me LOL Is there a way to go into the settings of the car and turn off say the lane assist or other features or does the dealer have to. I'm getting the safe and smart package only for the memory seats and BLIS

I think you are misunderstanding how the lane keep and blind spot monitoring work.
Even when fully active they won't prevent your from sliding over a lane and smashing into a car when there is no room at all. So if there's room, you'll have no issues.
BLIS or blind spot monitoring will illuminate a small LED in the mirror when someone is next to or just behind your car; the typical blindspot area. If you put your turn signal on while the light is illuminated, it will blink but there isn't even an audio warning, let alone something that stops you from moving over.

The lane keep only works above a certain speed. I think it's 45 mph but I'm not certain on that point. So in stop and go traffic it wouldn't be doing anything even if it was turned on. Above 45 it will vibrate the wheel and gently nudge you back in to your lane if you move close or cross the line without a turn signal. Even then you can easily over ride it by simply applying firm pressure to the steering wheel. Use your signal and again the system does nothing.

You're 100% correct, I'll just reiterate that you can turn off the steering wheel "nudge" if you want to.

I have zero experience with the Ford safety systems, only what my buddy told me how his system was on his Cadillac which is the GM system so his could be exaggerated or the system in fact has more control than the Ford does. That's why I was asking here to get other people to have come first hand experience and to comment on the Ford system

Personally I think your buddy is exaggerating...a lot...what sort of liability would that present if a car system literally prevented a driver from steering the direction he wanted or needed to go?

it never prevented him from changing lanes it just fought him a lot more than he thought it should

I think most systems today aren't overly obtrusive but it is going to get much worse.

From a government perspective, it won't matter if something reduces safety for individual drivers. What will matter is reductions in total losses. And that is not something new. Remember automatic seat-belts? You were less safe in a car with them than a car with regular belts IF you buckled up. But a lot of people didn't, so the responsible people were put in jeopardy to save a bunch of people too stupid to manually use belts.

In Germany, I believe there is a law being discussed that would make it illegal for your car to choose an action that is best for your outcome alone. Cars will assess the best possible outcomes for all parties in a situation or toss a coin to decide to save you or to save someone in another car. Of course that won't happen until cars are smart enough to have a basis to make those decisions. Then again, Detective Spooner would have drowned without such BS.

Personally, I'm taking up smoking to reduce the chances I'll live to see it.
