[ANSWERED] Why no blind spot detection?
Original question is here.
tbogdan asked:
I am thoroughly enjoying the 2016 Z51 A8 I recently purchased. Very impressed with C7 interior and all of the features that come with the 3LT. I am curious why Chevrolet would not put blind spot detection on the Corvette, especially when the small window behind the driver is obstructed by the driver seat when merging left or changing to the left lane. This is available on other GM products (LTZ Tahoe, for example).

Many of the questions on this forum relate to trade-offs in the vehicle design process. Side Blind Zone is a perfect example.
Generally speaking, we tend to err on the side of not having a lot of alerts that would interfere with the joy of driving. The SBZ feature was just emerging as a feasible customer feature as we were designing the 7th generation Corvette. We thought very carefully about including it in the program since we knew other vehicles were going to offer it. SBZ uses sensors located on the rear outboard corner of the car, just behind the fascia. That is precisely the location we needed to package our race-derived transmission and differential coolers. Having heat exchangers in the back corners interfered with both the physical space need for the sensors and disrupted their performance. In the end, we prioritized vehicle performance over a new feature that we were not sure would be a strong customer desire. We have gotten similar feedback from several customers asking the same question. SBZ does seem to be gaining good acceptance from customers so, although not feasible in the short term, we will strongly consider that customer desire in our future plans.

Seriously though, it's not hard to use mirrors to see. Kinda like what people have been doing since the Corvette first came out.

Im with you Baylor. If anything I would have preferred more luxury accoutrements then safety equipment. That the new Camaro has a heated steering wheel for example (among many goodies) while still costing so much less does annoy a little bit.

I would have liked to have had BSA. I have my mirrors set the way the NHTSA suggests.
I'm able to do this because the fenders are so wide that I can still see it in my mirrors satisfying my desire to see some portion of the car.
That said, I still like the visual warning for when I miss seeing a car enter the blindspot. It has happened where a car in the lane adjacent
is traveling much faster than the posted limit and I may see them in my rearview one instant and they are in my blind spot the next.
I appreciate the information on why it isn't included. What I took from this "Having heat exchangers in the back corners interfered with both the physical space need for the sensors and disrupted their performance. In the end, we prioritized vehicle performance over a new feature that we were not sure would be a strong customer desire" is what I stated earlier, that GM didn't think people would want it enough to devote R&D or $$ into incorporating it.
Considering how many GM vehicles from 2014 that did have BSA, I doubt there was any real discussion taking place like "Gee, do you think a Corvette owner will want BSA?" and someone saying "No way man" when just down the hall the Cruze, Equinox and Malibu design teams were asking that same question and arriving at the opposite answer. Cars these days are not so singular in their purpose, BenCasey wants more luxury in his Corvette, so concluding that a sports car buyer is only performance driven is short sighted.
Ok, now go on, yell at me for not just accepting the reply and keeping quiet.

CAS is great.
As long as it DOES NOT use police band radar!!!!!!!!!!!!
So far, too many do.
Quit using this!!!!!!!!!!

My wife's new Explorer has blind spot sensors and I find them annoying and wish I could disable them, which of course is not an option. They go off all the time in parking lots to the point of being useless and annoying. I for one am glad the C7 doesn't have them. I have over 10k miles on mine and have never come close to hitting someone in my "blind spot" because I have my mirrors adjusted properly so there is no blind spot.

If they would actually update the government regulations to allow them to replace the rear view mirrors with cameras, the blind spots could be really eliminated without all the annoying warnings and other nonsense which still aren't 100% reliable.

Have them on the wife's Acadia Denali. They just light up when something is is detected, no noise I'm aware of.
Weave just off center and you get noise Both can be turned off if desired

If you can still see some portion of your car in your side mirrors you don't have them adjusted properly.

The Z06 fender is wide enough that a slight body shift to the left and I can see it. I for one like the BSA system my Porsche uses. I've liked it in rental cars that were so equipped. It's not a crutch, just an aid. I like being aided when ever it doesn't interfere or restrict my freedom to make unilateral decisions, unless its going to save my life!

Don't like them myself since they do indeed interfere with the driving experience. This car has so much power I always roll on a little throttle before changing lanes as I check mirrors. Anything in your blind spot will then be far enough back to be visible.

Sorry, I don"t buy that answer. Look how long that we had to wait for radio controls on the steering wheel. Just seems short sighted to me. I'm p.o.'d that the Cruze has BSA and lane departure but not my car which cost 4X as much$$$ bs, I say. Paul

Yup, my 2014 Impala LTZ has all the safety features. Forward collision alert, curb and lane departure and cross traffic backup alert camera . But the best one is BSA .
If I had to choose just one I would get BSA for my 2015 Z06 You would think the amount of money we payed for our vettes that we would have more safety features than just a horn and backup camera !!
Just my 2cents !

I absolutely love my Corvette and really appreciate that Tadge takes the time to answer a number of our questions.
That said, it would have been nice if the "race-derived transmission and differential coolers" actually worked and the Z51 had indeed been "track-ready" as represented.
My 2010 Mercury Milan Hybrid had cross-traffic backup alert and blind-spot alert systems, for crying out loud.
I admit to not being an engineer, but am quite surprised that some really effective safety technology items apparently were not more seriously considered. Hopefully, such features will be incorporated in the near future.

I can show you a bunch of more expensive cars that don't bother with that nonsense. Ferrari, McLaren, etc. Don't buy those either, the Cruze is better.
Given the choice, I'd so much rather they had put more engineering time into cooling issues than blind spot detection.

You don't have to buy the answer. It's the realities of development. You don't like it, buy a Cruze.

Two things can be true at once. Those other cars can exclude BSA while the Corvette includes it. Viola!
There isn't a single logical rational to exclude a safety feature.
Mr Macho Bravado can turn it off or ignore it. My Jumpy can look at it every second and the casual relaxed driver can use is\t more conventionally or like me, when backing out of the garage at night.
Not that it matters because I don't drive my Z at night because of the fracking headlight shake due to a design flaw that secures the headlight to the fender but if I did, my garage doors are 9' wide. The sides of the garage door frame are difficult to see at night as I am backing out of the garage and the Cayenne's BSA just makes it easier plus their BSA is tied into the camera showing an extremely accurate illustration of the vehicle and how close I am to the nearest obstacles on all sides.
Even if I never need it as an actual BSA while driving, for this reason alone I am glad Porsche offered it.

I can live without blind spot warning. However, I have to tell you that my 2015 convertible is the only rag top I've ever owned that with the top down I have to still look over my shoulder to make sure there's not a car hiding in the blind spot.
Every other convertible I've ever owned, you set the outside mirrors so when you lean over you can just pick up the back corner, and the interior mirror just squared up and you're good with the top down. No blind spot. As a vehicle leaves the interior mirror it's picked up in the outside mirror.
Not this car because the interior rear view mirror isn't long enough to cover that wide-a**ed rear end.
If it was about 2" longer that would be nice. And don't get me started on the awful rear glass that isn't tall enough on the convertible.
