Blind Spot Issue?

I have a 2017 F250 6.7 with the blind spot indicator system. We also have a Porsche Cayenne with a blind spot indicator system. In the Porsche, with the indicator off, you can safely pull over without even using your mirrors. In my Ford, cars are too close to pull over into the next lane with the indicator off. The indicator only comes on when the car is right at my bumper. This does not seem right to me. I also think that the passenger blind spot indicator system works better as the indicator seems to come on well before the oncoming car is at my bumper.

Opinions appreciated!

Unlike the girls in my family, I actually use my mirrors to drive. With the lower mirror, the convex wide angled ones, I have no blind spots. I always trust my eyes rather than sensors.

I use my mirrors also. That's how I know the BLIS is an issue. Otherwise, I'd be writing because I hit a few cars.

I've noticed the same thing in the wife's CX-5. It casts a much longer path than the truck does, too long in my opinion. Either way, I guess I'm old-school too, and just use it as a secondary warning or a double-check. It would be nice if the auto-makers had more consistency/standardization in design with these techy safety features.

My wife’s tundra has good mirrors (no where near as good as the sd) but the blind spot monitoring system does work very welll. We have a canopy on that truck so visibility is a little limited and it isn’t equipped with a lower convex mirror. The blind spot system came standard with the Toyota and I was kind of surprised that this system wasn’t standard on the SD trucks.
I don’t have it on my SD but I also don’t have a canopy or a camper on the truck so I don’t find it necessary but if I did and I had paid for it I would also be a little irritated. They charge a fair buck for that option, it should work.

My secondary mirrors are useless for the blind spot because they are aimed down so I can see how close my rear tires are to the lane demarkation on my dually.

I rely on my BLIS but I also look over my shoulder because I'm not yet comfortable in heavy traffic with this beast of a truck.

The BLIS on my Subie Outback and Odyssey van are way better.

Also maximum distance you can set the adaptive cruise control on the SuperDuty is too close IMO if you're pulling a heavy trailer. The max distance you can set to follow the car in front of you is way closer than what I can set it at on my Outback.

I'll have to admit, I got a little spoiled with the blind spot indicator on my wifes '17 Yukon Denali. It works really well IMO. I was very disappointed in the system on my super duty. Oh well, guess I'll use the mirrors like I have for the past 25 years.

I agree 100%! It seems as though they set the sensor range to about 3” off the back bumper. It pretty much makes the sensors pointless IMO. There’s really no use for them and they give drivers a false sense of security.

We also have a Cayenne and I test drove an F350 with BLIS before we bought our current F350 without BLIS. The Porsche system is top notch works 100%, the system available in this truck is really not up to par. I noticed the same thing about cars too close when the BLIS system activated. Because of the option's poor performance I didn't chase a truck with that option. Hopefully the 2.0 version of the BLIS system will be better when its developed.

You all do realize this is a "Blind Spot" indicator system, not a safe to merge into other lanes system. The system works exactly as intended by alerting you of cars possibly in your blind spot (which if you are using your properly adjusted mirrors is next to impossible anyway.) If a car is past your rear bumper, it really isn't in your blind spot at that point and you should be able to see it approaching using your mirrors. Even if you have your tow mirror angled down, as I do, to see the lines for your rear tires, you can still see most of the lane as the mirror is convex.

Every other manufacturer add a safety margin behind the vehicle. It is just odd that Ford decided to set theirs to the exact vehicle length. Having it set with a small buffer would make it a much more useful safety feature.

This is the first vehicle I have had with BLIS so I have had to force myself to use the system as I am so very locked on to using mirrors after so many years of driving with them.

BLIS is a nice safety system and I am sure with time I will learn to appreciate it more but I am very picky about my mirror positioning and with this and previous trucks I never look over my shoulder. With the mirrors I add there are no blind spots.

I have even added small bullseye mirrors on each side so I can see parking lot lines when backing into a parking space. The position I have my convex mirror in does not let me see those lines as well as I like.

My son just bought a new Honda for his family car and I much prefer the BLIS warning light location on this Honda. The lights are located inside the cab in the front lower window corner on the doors. I also am jealous of his paddle shift system!
