Blind spot detection.

[Pluto1]

Just wondering how it's been working for other people.

When I first got my car last year around June and for a while after that until the V10 update, I'd consistently get visual on dash for the cars that are in my blindspot by highlighting them red as well as the lane turning red if I use turn signal. (at least while I was on autopilot).

After the V10 I think it has been inconsistent in showing cars highlighted in red when they are in my blindspot when I turn on the turn signal.

The dash still shows the car accurately around the car but sometimes highlight them and sometimes it won't.

I was just wondering if anyone is experiencing same issue.

Tesla does not have dedicated blind spot sensors. It relies on rear ultrasonic sensors and the side cameras on the fenders.
BSD on Tesla is still beta like AP to me.
IMO l, it will get better with the future updates.

That feature never worked for me, someone started a thread about this a few days ago so while I was out yesterday I got next to a car doing about 65 and hit my turn signal as to turn right into the car next to me, nothing happened. March 2019 SR+ No AP, 2.5 HW

BSD leaves a lot to be desired in the Tesla model 3
not sure why they didn't just go with a light on mirrors like lots of other companies

almost side swiped 2 cars at different times changing lanes in bumper to bumper traffic.
A very common scenario, you're in the slower of the 2 lanes bumper to bumper. You see an opening in the left lane... you steer left, nudged the go pedal a little, only to find another car next to or just behind the rear driver side door or quarter panel.

There are no blind spots with properly adjusted mirrors. It took me a few days to get used the proper positions.

A lot of Model 3 design was with the idea there's be no little to no manual driving pretty shortly after release.

Why waste $ on lights the computer driving won't care about?

See also the lack of rear radar and cross-traffic alerts- the car autoparks by backing it, so it'd never need to back and and never need rear cross-traffic detection.

Heck at Autonomy day last year Musk suggested there'd be no-steering-wheel Teslas out by 2021.

Well yeah that sounds good and I can understand that, but just looks like we are very long off from Teslas having no steering wheel and doing all the driving

Unfortunately for many of us, the driver side mirror was poorly designed. It cannot reach where it needs to be for a proper a adjustment. It doesn't go 'out' far enough.

So its not just me then! only car I've ever had that actually has a blind spot lol.

No problems...consistently well for me.

This is 100% false. You can follow the guidelines and still have massive blind spots based on height, seat orientation, mirror size and mirror range.

I had bad blind spot issues with the 3. I recently purchased convex mirrors from Suma Performance and no longer have that issue.

Yes, this is the same for me.. i cant trust the side mirrors like i used to in other cars.

How To: Adjust Your Mirrors to Avoid Blind Spots

Very true, and above instructions are good advice.
But this implies that one can adjust AND actively use mirrors properly, for BSD and other functions.
Unfortunately, this is not likely to happen on Model 3's for at least two (2) reasons:

1. Model 3's side view mirrors are not wide enough, and don't swing out far enough to provide proper coverage angles.
2. Tesla preaches, and most folks on this forum trust and rely, that Tesla's software will take care of BSD and most other driver's responsibilities.

To answer OP's question - yes, the v10 blind spot threat (red car) notification has been inconsistent and temperamental. You should rely on it just about as much as you feel comfortable relying on all other AP features.

Namely - trust, but verify at every turn (pun intended)!

After one year of ownership I still miss having bsm indicators on the exterior mirrors.

Why do images of Vehicles in front of you appear at a longer range then vehicles approaching from the rear?

If I use my turn signal and there is a car, I always get a red vehicle warning. I might be in the minority, but I always use my turn signal.

I mean with turn signal on. I expect the cars in my blind spot to turn red when they are in my blind spot and I engage the turn signal but it is not consistent at least my experience.

I guess the idea is to drive fast enough that it doesn't matter.
But yeah, I thought my mirrors were broken.. but nope, they just don't go far enough.
