I think you are missing the original person's point. It's not that they don't use turn signals; they are probably like myself who doesn't choose to activate their turn signal until they know it's clear to change lanes. This is a courtesy to other drivers as the driver in the lane next to me doesn't have to worry about will they/won't they if my turn signal is activated while the lane is NOT clear.
Well....so.....kinda, sorta. I don't know, the BSM in my BMWs never was that great. However, my wife's Mazdas have had great, simple, BSM systems. The Mazdas set a light in the mirror, anytime anything is detected in the blind spot. Then they beep if you signal. Simple, great system.
FWIW, most of the shortcomings here can be attributed to: Tesla expected the car to drive itself years ago so designed for that. Why bother with cost of a mirror-light system when the car will handle it on its own? Why bother with rear cross traffic when self-parking backs into spots (which is inherently safer anyway)? Now of course they've missed years of goals on actually getting self-driving working so those choices don't look quite as good- but that's the idea anyway. (see the removal of gear shift stalk on the new S/X as another example of this thinking- the car'll take care of all that for you, ya know, eventually)
I wonder what percentage of new Model 3s come with FSD? I know I didn't pay for it! Give me cross traffic and BSM for like $10.00 in additional hardware vs. $10,000 for FSD which doesn't really work! When I can get in and tell the car where to go, and trust that it will take me there with no interventions, and without pissing off everyone around me, MAYBE I would pay 10K at that point.
My wife complained about the lack of BSM, as we had in our last car, but she now loves autopilot and TACC. Yesterday, with her driving me to a doctor's appointment, she just got in the center lane and let the car do the rest. During the drive, some idiot on our right tried to merge into our lane too early and our M3 braked and turned a bit to avoid him. I'll take that over flashing BSM lights.
But they are not mutually exclusive. The car could still do that AND have a flashing light in the mirror to warn you of someone in your blind spot when you want to change lanes.
Yeah.....but he's not looking in the direction he is traveling.... hope nobody brakes in front of him.
I agree, The BSM in Mazda's should be the benchmark, I have a Mazda 6 and 3, and both are very effective.
Nonetheless, that is the only way to make sure there is nobody in your blind spot. Don't trust the car.
While that is likely true, I just do not understand it. If FSD ever becomes a reality, it will be a nice feature. However, I did not buy a car that goes 0-60 in 3.something seconds to have a computer drive it full time!
I have never seen it alert me on the screen or anything but ONE time I hit the left blinker to get ready to pass someone in front of me and didn't see anything on the side mirror so I started to turn the wheel. The moment the wheel started rotating, the car beeped at me and showed me the car in red on the screen. I then double checked the mirror and there really was a car accelerating past me. That's when I found out there really is a blind spot monitoring. It's too bad it doesn't show you all the on the screen that there's a car in the blind spot.
