I'm guilty of occasionally straightening the curve, in especially safe situations of course...

 
On a “closed course” no doubt. ;) 

 

I do it all the time in the fire truck. I do have the advantage of height for sight and the warning lights. :) 


To be more detailed, it’s not so much for speed but you have a guy in the back trying to get his turnout gear on and the smoother you can make the ride, the easier it is for him.

A less famous exploding whale.  Fair warning, do not watch while eating.

Pedal misapplication

Doubt it as the brake lights did come on initially...... long time for a misapplication:dontknow:

The EventDataRecorder in the vehicle knows for sure, unless the Tesla Mothership can alter/erase that info. If I was investigating the crash(es), I would recover the EDR asap and put it in a Faraday envelope until the info could be downloaded.

Tesla is helping with the investigation, but says the video footage shows no brake light (meaning no foot on brake pedal).

 

 

 

Perhaps the brake lights were not on because the system failed?

I’ve seen footage of people who crashed into a wall with their foot accidentally on the gas…and then put it in reverse and crash into something else because their foot is still on the gas…and then put it in drive and crash for a third time, having never realized their foot was on the accelerator the entire time.  

 

it’s certainly possible the car is entirely to blame. But without any info other than the video, I’d speculate that the autopilot spontaneously aborted the roadside stop and started tailgating the scooter, at which point the driver accidentally hit the accel instead of the brake.  
 

Teslas use regenerative braking for light decel, which would be “drive by wire”, but they do use friction brakes for heavier decel.  Does anyone know whether those friction brakes are also drive by wire?

the article you linked to is subscription only.  I looked up other articles about that crash, but didn’t see anything that had clearly concluded what the cause was.

 The cause has never been determined, or if it was, it was never made public.  NTSB declined to investigate, said they could have gotten telemetry data if they wanted to, but did not, and refused to provide a reason why they did not investigate. "...Tesla checked their system and they did not receive any telematic data from this crash. ...The vehicle ECM would likely have retained the data." - but there have been no reports that the data was ever collected. The driver said  "he lost control of his brakes and was unable to stop". The car traveled nearly a mile at about 70 mph, mostly on a 35 mph downtown street. Columbus police have declined to release information from their investigation, including video from traffic cameras showing its progress.

All cars are required to have an EDR. It permanently stores the 5 seconds of data prior to a significant Event, usually an airbag detonation. The data was there, the Feds allowed Tesla to cover it up....... No other possibility.

Interesting, but doesn't say they are mandated

EDRs are not mandated on new vehicles, however, if they are installed, they must meet US DOT requirements governing the data they collect.[2] As of 2004, an estimated 40 million passenger vehicles are equipped with the devices.[18][19]

Is an EDR required by law?

No an EDR is not required by law.

I sit corrected. There was a big push to mandate them in 2013 and I thought it had gone thru.:dontknow:

Carmakers have been putting them in cars starting in the mid 90's with higher end vehicles and progressing down to less expensive ones ever since....... I have no doubt that Tesla has them in their vehicles, nor do I doubt that the Tesla Mothership controls all.:java:

LNG tank storage on top of the truck?    I would have guessed it to be a safe zone.   They may be going back to the drawing board on that one.

.... and yea,  he wasn't the sharpest tool in the shed :4317:

Any SR-71 Fan’s out there?

 

If you look really close, you can see Roug hiding behind the cab watching for scallywags.  :)

 

On a more serious note, my instructor who taught me spins and helped me achieved my CFII was an SR 71 pilot.  He didn't say much when asked other than yow.... it's pretty fast and fly's pretty high.  Dude was a Colonel and fearless in an airplane.  Flew a couple of airshows with him.

Pretty interesting.   The guy put together a lot of innovative contraptions for entertainment purposes.

 

We have a bird feeder with a baffle and have yet to see any our locals make a successful climb, so I am getting a kick out of the video.

Toured the Subaru plant in LaFayette, IN in late '19.  At the paint stations, the guide told us paint room employees were given a list of hair and skin care and body wash products they could/couldn't use as some creams, shampoos, etc. shed particles that caused dimples in the paint surfaces.

Back in '93-94, I was part of Special Operations Training Group.  Within that group, I belong to the Cliff Assault section and we were responsible for training Marines to climb rocks.  Additional duties were Helicopter Rope Suspension Techniques (SPIE rig, rappel and fastrope from all the birds) as well as Urban Assult (climbing buildings, inserting into windows from the roof (oh man, that's fun), as well as how to get down them fast).  Had recruiting not jammed me (I was NOT a volunteer for that gig), I would have also had the luxury of being trained with our Mountain Section,...and their trips to Thule Greenland to ice climb, cravass rescues and whiteshitassault stuff.  The crew that did that said it's much easier to ice climb than rock climb because of the ice axes and crampons,...pretty much make your own route.  Sooo, I missed out, I think it woulda been fun gig.

Trivia question 🙋‍♂️ rough number, (or maybe you know exactly :dontknow:) how many Marines did you take part in making?

'twas low over the course of three years as I was an honest recruiter.  68 actually made it. 

 

Marine recruiters statistics are a bit odd as they must graduate bootcamp for us to have them count (like you can control an illness or injury).  I think other branches don't have that against them.  The requirement at the time was three a month, if you look at my overall, it ended with a 1.8ish.  I think I only had five months total where I hit the three or more for a given month......I survived recruiting.

 

Many recruiters I knew would have high numbers of four, five, six a month,....but, here's the kicker, they didn't stick.  Either those would drop out of the delayed entry program or drop out of bootcamp.....thus, it went against them.  The saying goes, "recruiting is nice, but shipping is king", meaning that you can recruit them all day, but you gotta get them to bootcamp AND make sure they graduate.  My retention rate was high.  I think it was over 90% would go to bootcamp and 98% graduated.  Only one of mine went as an "open" contract (no guaranteed MOS), yet, he actually got what he wanted (mechanic).

 

With my primary MOS of infantry, I only enlisted five in the grunts (I couldn't talk them out of it),....once I gave them the "where do you see yourself after you get out" spiel and "you really gotta like misery", they opted for technical jobs.  I would put kids on the phone with recruiters that primary MOSs that the kid was seeking, yet, never, not once, did I have a recruiter call me to explain to their applicant what the grunts was like.

 

I always started my presentation with misery, how bad you will be treated, how miserable you will feel,....the long weeks away, long months away, no contact with friends, family.  My applicants would get the worst the Marine Corps had to offer.  Only then, if they were still interested, would I go into the happy shiat, the fun stuff, benefits and the like.  You gotta be real good,.....really good at rejection.   36 months out there, didn't take a single day of leave (you'd get behind).  Summer months was seven days a week.  Cooler months, six and sometimes seven days a week.  M-Thur was 0800-2000 minimum, I had appointments at 2300, 2400, 0100, 0200 at times (meet when you can).  Fridays, 0800-1800ish (kids disappear Friday evenings).  Saturdays could be 0300ish-1700ish (if a meeting was happening, you gotta pick em up and drop em off), no meeting it was 0700-1300.  Sundays were early as well as you had to get those that were shipping back up to MEPS, some, we had to drive up (two hour one way if you did the speed limits).

 

Recruiting was a love-hate-hate relationship.  It was nice being in the civilian world in uniform, but it was miserable because you really had no control (if you were honest) on the decisions that these kids make.   The best thing outta recruiting,.......I met my wife.

If you've never had a CPR class, please consider signing up for one.  If that's not going to work for you, then at least consider reading this how-to guide.  The success rate is pretty low, but when it does work, holy crap, you've just saved someone's life.
