FSD…..A VERY DANGEROUS SETTING

wait till I comment on how often Tesla has you stopping to recharge to maximize charging efficiency during a 1,000 mile trip

Efficiency is poor at 85MPH

If you think my comments on an unsafe alarm was fun…..wait till I comment on how often Tesla has you stopping to recharge to maximize charging efficiency during a 1,000 mile trip….A Cyber Truck battery size that gives you 320 miles of range is near meaningless.

With these gas prices, I’m rich biatch .

This is on SH-130 toll road through Austin, which goes right in front of the Gigafactory:

Welcome to Texas

I was driving on SH-130 last month in my wife's Model Y. FSD kept alternating between reading the 85 MPH speed limit signs as 85 MPH and 65 MPH. Decelerating in traffic while everyone else is driving 85 is also dangerous.

Sell the Cybertruck. It’s not for you.

If the speed limit is 85 - which is in limited stretches of highway- set the car FSD toguyry and let the car decide how to safely drive in the surrounding traffic - if your cybertruck is moving at 85 miles per hour - at the speed limit- than other drivers that wish to exceed the speed limit can go around your vehicle. These other cars are moving at dangerous and illegal speeds. So you’re upset that FSD won’t also accelerate your vehicle to illegal and therefore likely unsafe speeds. Put the truck in chill mode and sit back and relax and let the car drive in the slower lanes - safely. Your letting drivers violating the speed limit by 10 to 20 mph dictate your vehicles speed. The reality is over long distances - like 1,000 miles - your unlikely to maintain an average speed close to 85 miles per hour due to traffic conditions, stops to recharge, weather, speeed limits in the 70 miles per hour range are more prevalent. Worrying about traveling 90 plus mph for select sections of road on a 1,000 mile trip is simply pointless anxiety. Sit back and let the car do its thing. You just want the car to violate the max speed limit 10 if not more mph. Your simply a control guy that has issues handing control to FSD.

DRIVE YOURSELF - and drive as fast as you dare -

I am more concerned with FSD driving to close to the car ahead at all speeds. I would like a setting for setting setback from the car ahead and as speed rises this setback safe distance should expand.

Allowing the most foolhardy drivers to set your speed is simply foolish and could get you killed or at the minimum an expensive ticket.

Your not a good FSD candidate / save your $99 a month.

are you sure the sections of road were actually 85? there are spots where it dips into 65.

I have never seen a sign showing 85 as a limit! In Florida 70 is top speed I have seen! The truck may not be the right choice of transportation for someone who wants to drive at a higher rate of speed for whatever reason. I’m betting Tesla engineers decided 85 is fast enough for FSD. Maybe it will change in future. For me driving at higher speeds is when I want control.

Nope, this was already addressed above. FSD used to give us a top speed of 90. That only changed because they took away the radar and went to vision only and it hasn’t been restored to the prior top speed yet.

The top speed of 80 was rough when the first disabled radar. Plus phantom braking skyrocketed at first.

This is one of the limitations of camera based imaging. Standard camera frame rates are 30 -60Hz, which directly equates to the distance of travel between frames - would be a fundamental limitation.

Would you trust yourself controlling a moving vehicle if you could only get an image every 20ft? Imaging driving using strobe lights instead of headlights - that is how FSD is seeing the world. By snapshots.

Well, in fairness we’re not really seeing things in real time either. We’re about 100 or so milliseconds behind.

Yeah it was kind of weird. (1) early days bad phantom breaking with radar, then (2) dramatically improved with radar and then (3) take away radar and it got way worse than it ever was before for a period of time. The early days had a lot of ping-ponging and periods of the system being practically unusable. We have come a long way and I can’t wait for 14.4!!! Bring on the sentience!!!

The early version of FSD v10 would basically abandon every left turn. Things have come a long long way.

The cyber truck had radar? Who knew, not me. Also did not know FSD top speed was 90 prior!
Last night I was in FSD and had to pass a long trailer on a dark two lane road so I hit brake to disengage punched it then resumed FSD after the pass. I guess I am use to having to do this. I’m sure if our speed limit was 85 here things would be different!

No.

Radar was in S3XY cars, they still install it on the S/X for whatever reason.

“Back in my day you could only make right turns and we had to do it uphill both ways! And your wheels were connected directly to your steering wheel … and even then only the ones in the front would turn!!”

They did until they stopped making them this week.

@Ken in Miami , the cyber truck never had it but the rest did and then they stopped putting it in the 3 and Y at some point and turned it off in all of the other others that still had it. Elon decided that radar was interfering with FSD and was creating confusion which is why they went to the stack that only used vision, but when they did that and took out all of the other sensors supersonic and radar — all of the functions that required accurate measurements were downgraded to prevent incidents. Not that they didn’t feel you could get accurate measures from vision only they just weren’t confident and decided to bake some additional margin of error.

Summon, FSD, distance warnings went from telling you exactly how far you were from something to just the heat maps that we have now. It’s the main reason that we don’t have dumb summon or ASS in our CTs.
