In the investors call last week Tesla stated that the problem is at the Gigafactory with battery production.

Here's a link to a summary of conference call: https://www.reddit.com/r/RealTesla/comments/7ao4m0/conferenc...

That forum is quite anti-Tesla (as opposed to /r/teslamotors). The whole Tesla thing is quite controversial - lots of haters, lots of fanboys.

Best advice I can give you: Read what both sides have to say and weigh the arguments. Then just stick with the truth you've always believed in - it's what everyone does in 2017 ;-)

IMHO two things:

a) "fast charger" is a loose term and is often used for anything exceeding 20kW. Superchargers deliver up to 140 kW (split between two cars) or 120 kW (to one car). That's why Tesla/Elon sometimes refer to them as "level 4 charger", although the specification ends at level 3. Other manufacturers are now getting on that train with (according to specification) up to 400 kW

b) The notion of the "average electric car user" does not take into account that yes, people drive less than 80km per day on average, BUT they go on the occasional road trip. And they don't want to have a car sitting around just for road trips. They want one that can do both (commute & roadtrip). That's where the supercharger network helps

Initially ludicrous mode was not just a software update. You could get it on your (already delivered) MS P90D, but had to bring it into service. They changed a fuse and activated ludicrous mode in software.

Of course, today all Tesla P100D get built with that fuse already in place - so it's "just a software upgrade" today.

There's quite a bit of electrical magic going on for a fuse to be able to handle insane current bursts while retaining a good response time in case of a catastrophic fault.

> Lindsay Meyer, an entrepreneur in San Francisco, said Mr. Caldbeck put $25,000 of his own money into her fitness start-up in 2015. That gave Mr. Caldbeck reason to constantly text her; in those messages, reviewed by The Times, he asked if she was attracted to him and why she would rather be with her boyfriend than him. At times, he groped and kissed her, she said.

Nice! Here's grade-A material for the 46. President of the United States of America /s

edit: added /s because it apparently wasn't obvious to some out there. Further clarification: This is a sarcastic comment on the fact that the USA have a president who has publicly admitted to sexually harassing women. With that person at the helm of the nation, how can anyone be surprised by others behaving similarly?
