FSD in the CT has saved me from incidents with bad drivers 3 times and almost killed me twice. All in all it gets a +1 from me (y)

Human drivers suck. I almost exclusively use FSD these days.

In 2018 I got rear ended by someone who fell asleep going 70MPH while I was STOPPED in stop and go traffic - ever since that day, I’ve refused to drive anything that didn’t have advanced ADAS systems.
My biggest complaint with FSD is it does not slow down soon enough to SLOW DOWN the driver behind you. I got rear-ended 40 years ago. Never since. Why? Because I slow the driver down behind me by leaving a lot of distance between me and the car in front of me.

FSD - especially with the CT - slows down (IMO) last minute. This does NOT send the right message to the driver behind you that is tailgating the crap out of you!

I can trust FSD almost all of the times except for when another driver does something stupid. Primary them cutting in front of me as a blind spot lane change maneuver. I have taken over control every time this has occurred (that I am aware of). Any feedback on how it handles the situation for folks that have had actually let it decide?
It does a better job that you. I nearly had a head on collision but the CT turned before i could even grab the wheel. My wife became a believer in FSD after that. She asks me to let Elon drive.

My CT handles that no problem

My 5 year old ask me are you or the car driving . I said what . He said again I said I am he said out the car back on . Them back seat drivers .

I should reiterate that if I had not reacted and FSD didn’t react that I would have been sideswiped.
*** bit a an FSD rant warning***
FSD as it works now does not possess any 'strategy' it cannot 'anticipate' other driver behavior or intention.

When -I see someone driving towards me and I see them grabbing the steering wheel in preparation for a 'turn' I use this to anticipate their potential intention. regardless if they have the right-of-way or a double yellow line is between me and them. ;)

FSD and AI in general have completely 'no' sense of 'future intent/strategy - they respond to events as they occur and don't have any provision to anticipate. I write software for my work, including vision systems. The advantage computers have is they are fast and can respond fast - however, this is not the best way to navigate a vehicle among human driven vehicles.

My evidence is using FSD where I am on and *will be* driving on a hwy for 18 miles - FSD will drive the entire way in the 'slow' lane - which is pathetic. How will this be when 50% of the cars are self-driving - shuffling along on the slow lane. - Compounded - by the fact that my CT with FSD to my determination COMPLETELY IGNORES a turn signal/merge/ request from another vehicle and just drives along its merry way, pushing them to accelerate or brake to get in front or behind me.

FSD lacks *any* sense of *courtesy* where when a hwy exchange is approaching - to move away from the exchange lanes to allow those vehicles making the exchange access. FSD does not have any provision to provide for 'other' vehicles or 'optimal' lane position for itself.

I did many years ago develop control software for some quite dangerous equipment and developed code that ran in parallel to the control code with 'predicated' and 'anticipated' changes and weighed that to balance the control codes response. Because if you loose an altitude sensor at 10,000 feet the plane autopilot will pull up - however, a human would not respond that way - a person would apply 'common sense' and know they *were* at 10,000 feet a moment ago - and still are - so doing nothing to the controls is the correct response in the short term. Then sort the sensor readout error.

Using cameras for vehicle navigation is difficult - as you have to extract distance information - which cannot be done directly from a camera system. [you need 2 cameras actually]. Vision systems have many, many issues that make is hard to do, our world is fuzzy and does not have clean edges.

Also, you cannot use raw processing power to solve the problem. There are too many layers to autonomous navigation that can tax the most powerful processors. Nature has solved some of these problems in fascinating & elegantly simple ways. Which should be mimicked in FSD in general.

You need to put in hurry mode and increase your speed. In chill mode it stays in right lane. I keep mine in hurry and beast mode. Don’t have the problem. You can also turn on left turn signal and it will move into left lane if you have max speed correct.

What mode are you using? Mine in standard likes to stay out of the right lane, even on a 2 lane highway. Courtesy is a good thing, but I won’t judge it based on that. If a piddler sits in the left lane until it’s his time to exit, yeah, it’s his job to brake or accelerate to get around you. It’s not Tesla’s problem to make life easy for pathetic people.

How often can this possibly happen to you? When other cars just merge directly into the side of your car, requiring you to serve out of the way or hard braking?

Doesn't FSD v14 now include intent/strategy? I am not sold that you need 2 camera's to produce a 3D representation. I had always understood that you could achieve this with multiple frames from a single camera video feed due to movement and then be able to infer a 3D image from the differences of the angle of objects. Very similar to a persons ability to navigate safely with only eyesight from one eye.

It is not a daily issue, but I would say a bimonthly event would be a fair assessment. I am also a low milage driver as well. 5k-6k miles per year.

Single camera 3D image extraction is Photogrammetry, requires specific movement about and around the object. I have used these systems which work well for 'scanning' objects.

Photogrammetry does not apply a scale to the object, you can scan your wallet or a barn and it will create a 3D mesh model. As I mentioned it requires massive computing power and memory to mesh together continuous image frames - Having used these systems you have to spend time fixing the mesh model to close the mesh to create a singular 3D object where all the surfaces connect with each other.

You're correct: one eyed people and even you & I in the dark can navigate our homes - because we have kinesthetic sense, which cameras do not have. This is created in FSD by using the vehicle GPS and speedometer.

Also consider the camera frame rate is fixed whereas your vehicle speed is not - so how can you 'infer' a distance change between the image frames across different speeds?. Use the speedometer - however, we'd assume the object we are looking at is 'not' moving?. Also what if the object is growing? that does not necessarily mean it is closer to the camera, or moving at all.

So there are 'infinite variables' to the problem where your software does not have memory or computing power for infinite variables to calculate.

Our bodies are amazing!. Nature and evolution has created a very sophisticated and seeming simple system - which we strive to recreate in artifice.

Jack
