ultrasonic sensors are probably necessary as cameras don’t have a sufficiently wide field of view at super close range. E.g., if you’re inches away from an obstruction that is very low in a parking spot.
Ultrasonics can't actually do that either though.
It's why the car still hits curbs (and sometimes other cars) when parking itself.
It can see fairly close- it can't see VERY close if the object is quite high or quite low.
In my "If Tesla wants a real L5 sensor suite" idea; the car has fisheye cameras low on the bumpers- which would both provide a genuine overhead 360 parking view, and provide safe self parking even in narrow/tight spots where the front cameras that can't see below the hood line can't tell if there's anything low/in front of the wheels.
If it had em to the sides too it'd let it see better around tight corners where now the car has to keep inching up into traffic to see to the sides with the B-pillar cameras... (and in the back it'd provide better to-the-side cross traffic view backing out of something).
Radar is only necessary for superhuman performance.
Why would we
not want that?
No reasonable way to model it right now
They modeled robotaxis, and those don't even exist yet- and ask 10 people and get 10 different answers of the actual demand, the impact on "regular" car ownership, the real cost per mile, and so on.
The solar and energy businesses
do actually exist and we have a reasonable idea of the size of the addressable market, the current costs and profits, and so on. How's THAT no reasonable way to model, but RTs are?
Then I started think, once Tesla is a mature boring company, they will most likely start paying a dividend.
Elon has in the past explicitly said Tesla does not pay a dividend and
never will.
Not that he never changes his mind- but I certainly wouldn't base any long term investment plans on him doing so.
EDIT: I've gone back a month to look the various videos from this YouTube channel and the videos NEVER demonstrate the actual version number of the FW. Also, the views of the interior show different cars. Sometimes the mylar is on the center screen and sometimes NOT. Seems like they might be getting a hold of different cars at different times before they are getting delivered. And remember that during delivery the FW is updated to the latest. None of these videos demonstrate the actual version number of the FW.
So your premise is they somehow keep getting multiple, different, "new" cars that never had their firmware updated... but.... somehow ALL came from the factory with FSDBeta enabled, but also an old version of it? And Tesla hasn't caught on to any of this happening too?
Seems....somewhat less plausable....than "sometimes FSDBeta screws up, and the guy isn't afraid to include those examples when he posts video"
If FSDBeta did
not sometimes screw up, it'd already be in wide release after all.
