This is a great discussion! I am OK with Tesla's approach, I own just
enough stock to care that they don't go bankrupt from liability issues. I
think the are just being prudent. That makes me happy.
I also think that salvaged Teslas are far less valuable than the guy who
bought one paid and
Automotive CPU, MPU, ECU, etc. are often designed using in ASICs
(Application Specific Integrated Circuits) and nowadays FPGAs (Field Gate
Programmable Arrays). The software is not served up by a drive, or kept on
a flashable EEPROM, it is literally built into the silicon. Or in the case

I have several JLD temperature controllers in service about my lab and they
work flawlessly so far. Based on their performance I happily bought the
WattHour meter, but I haven't really used it yet. For the cost they are
certainly worth a try.

I can't see why I need a high rate of charge at home. If you are
economizing you never build for peak demand. However, many cars on the
grid charging slowly still requires some sort of compensatory, mitigating,
constructing effort.
This is not how batteries for cars will be charged at home.
The number of people buying the high end Tesla cars is and will be
exceedingly small and no concern for the grid operators. The number of
people who will buy a second probably much larger pack for their home (so
they can still charge after a number of cloudy days) will also be very
small. So
