Shocked! Model 3 has no blind spot detection [Update: yes, it does]

The Model 3 does see cars in the blind spot when the indicator is used. Perhaps a better option is that any object in the blind spot is automatically indicated (red line and/or red car), irrespective of the indicator. Not the most elegant solution but I would rather have that than nothing. Hopefully this is a "simple" software fix.

Agreed. A software update to address two things would go a long way. First, as you described, turn the cars red on the screen when they are in your blind spot regardless of turn signal status. Second, play an audible beep if your enable the turn signal when someone is in your blindspot.

If you don’t like these settings then they should just make them configurable via the menu so you get the behavior you prefer. Working on improvements such as these is a lot better than beach buggy 2 usb game controller support and chess.
 
iI personally don't want cars to turn red unless i'm signaling. I believe Tesla chose to wait for the signal to avoid distracting color flickering ALL THE TIME. I would be open to new visualizations for cars in your blindspot to help passively communicate their presence, but the red line and car should be reserved for attention demanding situations like you signaling when their is a car there. Just my $0.02

Pretty much every car with a blind spot sensor requires that the turn signal be on for it to activate. I don't see what the issue is here.
Exactly.

@moorej999 , the Model 3 does have blind spot monitoring. If you don't know how to use it, may I suggest some rather good reading?

Tesla Model 3 Owner's Manual

In particular, page 84. This entire page describes blind spot monitoring, how it works, and how cars are displayed in blind spots.

I have two cars (Volvo and VW) that show a non-intrusive, yet effective, indicator in the side view mirrors even if turn signal is off. The visual indication intensifies if the turn signal is turned on.

The pre-turn signal indication helps me decide if I should even initiate a lane change.
 
I think this is the problem. Very poor design choice by Tesla IMO.

Almost every other car with the blind spot detection we're used to in the mirrors, warns you BEFORE you try changing lanes. Tesla will only warn and intervene after you started making the move.

Also having to look in the mirror, over the shoulder and then back in the center screen and then back in the mirror... what were they thinking when they thought "yeah, this blind spot detection is a good idea, let's do this and save 50c by not adding lights to the mirrors"
I get it, change is hard.

But a change to stopping using blind spot detectors as the primary information source, rather making actual direct checking of the blind spot and the detector is used as the failsafe, is a very positive change. Time to rebuild the habit that you probably should have never discarded, or build the habit should have been trained in to start with.

So Tesla's idea of progress to the future means going back to the way we were driving before the usual driver assists... hmmm...
 
No, they don't. All the brands I've tested put the mirror light on as soon as there's a car in the blind spot.

You are correct. I was unclear. I meant that I don't hear an audible signal unless the turn signal is on. My car also has a little red warning in the mirror, but I don't rely on it. (In fact, I didn't even know it was there until I looked on my morning commute after reading this thread.)
 
None of my Porsche cars with blind spot alert require(ed) a turn signal to be activated.

Since Audi and VW are the same family, I would be surprised if they require a turn indicator to be activated either.
Ford Pick-ups also work this way... This is one of those areas where Tesla needs to stop crying "We're a Start-up..." with a mega billion dollar market cap, and going into their second decade, and start actually doing some real work on manufacturing a "good" product, in addition to an innovative one.

I like the car, and don't ever want to go back to ICE, but it needs some more "grown-ups" in management...

I am not sure if you have fully followed the thread. No one is denying that warnings are displayed on a center screen. But the natural tendency when changing to a left lane is to look at the left side mirror and and turn the shoulder to the left and not look at the center display turning your vision to the right when making a left lane change. That is counter intuitive and dangerous.

Tesla mucked this one up. Time to accept it.

Once you get used to the red or yellow light on the mirror or side pillar you safely avoid >99% of inappropriate lane changes because your subconsciousness makes you associate that light with the warning. In the rare 1% of the time that you are distracted and put on the turn signal the audible warning gives that extra safety.

The only way you can fail is trying to make a lane change without using the turn signal and also disregarding the warning blind spot light which comes on when a vehicle is in the blinds spot irrespective of your using the turn signal or not using it.

Great advice. Thanks!

Also true on my daughter's 2-15 Audi A3 -- only available in top trims, btw, BUT blind spot warning is automatically off during bumper-to-bumper traffic. The delivery specialist said it recognizes heavy traffic and turns off, otherwise it would just be on constantly. Not sure if accurate, since I never looked into it. however, I did test the alert in bumper-to-bumper traffic and as advised, it was off and stayed off, unless when I turned my blinker on.

in non-heavy traffic, it works wonderfully, and shows up in the mirror without turning on the blinker.
