The letter below is very good summary of the current situation.

Future weapons must go underground or deep underwater, or be mass-produced and attritable.

Radar-based stealth loses some relevancy when you are visually tracked by something all the time.

@PalmerLuckey @mattbramanti You mean you DON’T like gasoline that goes bad 3x faster and takes even more energy to produce? Heathen.

It’s so bad for when it sits over long periods of time, and most people have no idea.

@tesla_na @Brand0n Not allowing these across trims is insane. Performance in Marine Blue would be amazing.

@SawyerMerritt @Starlink Still not low enough. Most GA pilots fly only a few hours per month.

$100 is probably the highest reasonable monthly price. Hopefully SpaceX is paying attention and figures this out soon.

Looks like a Thorp T211 had an eventful landing at Sun N Fun. Luckily it doesn’t look like they got injured.

Runway 10L and 10R currently closed.

@Erik_Slot @FredLambert You are assuming things. I have worked on many Tesla car computers. When I get a chance, I will show you the chips.

The AG525R-GL modem supports eMMC, but really just for bootloader. Any logged network data would be long overwritten, and the modem would have prioritized eCall.

@CCOS @DataDeLaurier @FredLambert Trucks are heavier relative to the brake surface area, and brake fade is after long durations of braking due to hills.

It doesn’t matter in these cases. The brakes are not overheated. They will slow down the vehicle if they get pressed.

[Jason Hess @jsonhess]

Just fine. No leg days required, especially if you’re already pressing hard due to panicking from pressing the wrong pedal in the first place.

Here’s the parking brake vs. ~300hp.

If you want a detailed answer, you’re implying that multiple separate systems have failed in legitimately impossible ways.

The pedal monitor would kill motor torque when brake pedal is detected, and if brake sensing is randomly broken (not possible), torque also gets killed.

There are multiple sensors used on each pedal, with different voltage curves. There is no uncommanded acceleration, and there is no way for brakes to NOT be able to overcome the motors.

Was digging through old stuff trying to find something, and ran across this video of a Tesla drive unit on my old test bench fighting against just the parking brake, not even the main brakes.

Notice that the wheels don't turn.

So much for sudden unintended acceleration... lol

[Jason Hess @jsonhess]

@CCOS @DataDeLaurier @FredLambert What will it take for you to admit that you are wrong?

This is just the small parking brake vs. a ~300hp motor at ~75% power.

I will repeat this again: the brakes (which have physical hydraulic connection) will always overpower the motors.

@CCOS @DataDeLaurier @FredLambert Please tell me how software keeps your physically connected brake pedal from functioning.

Even with zero brake boost, you can stop a motor being given full throttle (which does not happen uncommanded).

[Jason Hess @jsonhess]

@GYoursefl50011 @FredLambert So do the car logs. No useful info for the missing 6 seconds.

[Jason Hess @jsonhess]

@schneider_chris @flcnhvy @FredLambert For brakes, the Bosch iBooster used still has a physical pump for manual, unboosted braking.

For brake-by-wire Ys (not the accident vehicle), there is sufficient software and electrical redundancy.

[Jason Hess @jsonhess]

@schneider_chris @FredLambert I am very familiar. Of course the car can request throttle and brake boost.

The car CANNOT override the physical brake pedal (which on this vehicle, is physically connected to the brake booster).

On the newer brake-by-wire Ys, the circuits are fully independent and redundant.

@Robotbeat GB/T, which annoyingly has an AC and a DC version.

@AnaEscobarShow It is completely normal to fly over the Savannah River Site as long as you’re above 2,000 feet. They were around 30,000 feet.

New Test Footage: AH-64 Apache attack helicopter executes rocket-powered launch of Altius-700.

This is the first time an Apache has employed a launched effect.
