Man In Tesla Model S Fire Explains What Happened
An anonymous reader writes "The three recent Tesla fires have raised concerns with a lot of people. One person who isn't concerned, however, is Juris Shibayama, the man whose model S burned in Tennessee. He says: 'I would buy another one in a heartbeat.' From the article: 'Shibayama said that he struck a three-pronged trailer hitch in the middle lane of the interstate. He continued: "About 30-45 seconds later, there was a warning on the dashboard display saying, 'Car needs service. Car may not restart.' I continued to drive, hoping to get home. About one minute later, the message on the dashboard display read, 'Please pull over safely. Car is shutting down.'" He said he had time to remove his possessions, even though, he said: "About 5-10 seconds after getting out of the car, smoke started to come from the front underbody of the car."'"
... to include "Car is about to burst into flame"
Muchas Gracias, Señor Edward Snowden !
At least the car was upbeat and friendly about its impending doom!
Translation - when you get in a WRECK your car does odd things. I am happy this person came forward and said "had a wreckand the car even warned me to RUN!"
Good design tesla.
Why's the current location a big problem? The current location helps lower the Tesla's CG which is good in many other ways. For a "sports car" I'd say the advantages outweigh the disadvantages.
These class of cars crash and burn all the time (some even split in two). Google if you don't believe me. Heck even other conventional cars crash and burn too- A friend's friends were burnt to death in a BMW after a crash - they were stuck and couldn't get out.
This Tesla model seems really safe in comparison. Maybe add some thermal sensors, have a "car about to burn" warning and we're good to go.
I can't believe they missed such a golden opportunity. The final warning should have been "Car will now Halt and Catch Fire".
I've know two people had trucks catch fire in the last year or so.... A Chevy Silverado and a Ford F150. You know what stupid things they did to cause this? One was parked in the driveway outside his house the other was being driven down the interstate.... Where's the relentless news coverage on these incidents? Even better is the response from the companies, for letters stating it was not their fault.
Too much information can be a bad thing. You need to communicate these situations in a simple manner so that they don't distract the driver too much.

You are correct that Tesla needs to analyze why the batteries are being compromised from what should be survivable incidents, a car's batteries should be protected better to keep them from being damaged by even the most severe road debris.
Actually, the described scenario of striking a multi-headed trailer hitch is probably WORSE than all that you described. It must of acted like a huge caltrop. You can't design for 'everything' and keep the car light enough to be functional.
Concrete curb - Odds are at least one of the wheels are going to hit the curb as well, raising the vehicle and lowering the strike area, and standard ones probably don't stick up as high as the hitch did. Even if not, you likely have a deflecting implact, not a puncturing one.
Road sign - These are generally constructed of mild steel and aluminum, as the worst the post has to withstand is the weather on the sign. In an impact it's going to be forced down of course, but then the rest of the sign will act as a lifting/distributing force on the car.
Trailer hitch - Designed to be able to haul trailers weighing 5k pounds and up, the balls are solid hardened steel and the post is generally at least 1/2 inch thick, again of hardened steel. Given the described hitch was a multi-ball type, it's entirely possible/probable that the thing weighed more than the average stop sign/post(excepting concrete), much less a mile marker. It probably impacted the car in a armor-piercing fashion much like a pike against a calvary charge.
I don't read AC A human right
The man has some seriously low expectations of a car.
For better or worse, by the standards of 'devices with more than a thousand pounds of Li-ion batteries right underneath the operator', responding to a massive puncture wound with a series of error messages and a controlled shutdown is pretty damn polite...
This doesn't necessarily mean you want to be the lucky driver of one; but I'm impressed that the system held off the worst of the failure cascade long enough for him to make it out alive, rather than just burning him into a grease spot and some mixed oxides right then and there. (I had the pleasure of one of Sony's defective battery packs back in the day, and after having to toss it, and the attached computer, off my lap in a hurry, I've never taken the term 'laptop' quite as literally. Those things go pretty fast, once they start.)
