I started doing this on Teslas in 2015, and back then it was more
problematic and a grey area for DMCA.  In 2018 they passed this wonderful
exemption for car hacking:
https://www.federalregister.gov/documents/2018/10/26/2018-23241/exemption-to-prohibition-on-circumvention-of-copyright-protection-systems-for-access-control

So after that I was able to help a lot more people without fear of
reprisal.  This was back when Tesla took a much more Apple-like stance and
would not even sell you parts for any car on their "blacklist".  This
included salvage and "grey market" cars (cars removed from the area in
which they were originally sold in).  Back then, there was huge demand for
Teslas all over the world, so I assisted a lot of people in Europe, Asia,
and other places.  I've helped people all over the world fix over 3000
Teslas. I created my own back-end the cars could connect to instead of
Tesla to get access to all the wonderful diagnostic data the cars collect,
and make that accessible to their owners.

In 2016 I had a good talk with Tesla's then President of global sales and
policy and warned him that Tesla's policies were going to make the cars
uninsurable.  That got his attention!   I explained how their policies were
making repairs harder, and devaluing cars once they entered the salvage
market.  He promised he would try to fix all this, and I think he did at
least put Tesla on a track to do some of it.   IIRC, He left Tesla in 2018
to go work for Lyft.

If you are a car company and do anything to devalue a salvage car, that
means when an insurance company deems a car totaled, they are not going to
get as much money in the salvage market, thus the total cost to replace the
customer's car is much higher.  It's easy to see what happens from there.
Tesla did not fix this in time, and the cars indeed did even get dropped by
some insurance companies.  Back then you could buy them at auction for
pennies on the dollar, because nobody knew how to fix them (no service
info), and no parts (Tesla blacklist).  Tesla's solution was to start their
own insurance division.  It helped, but didn't fully solve it.  The
repercussions are still being felt today, as Tesla's service division is
horribly managed and collision parts can sometimes be many months out, so
insurance companies are more likely to total an easily fixed car because
they aren't going to fork out 3 months of rental car payments for their
annoyed customer.

If Tesla would have really taken my advice back then 8 years ago, they
would be a much better company.  But Elon is a dick.   I still believe
Tesla engineering is world-class, and makes awesome cars despite him.
Elon, if you are listening, give me a call, I'll tell you how to fix it.

I was hired in 2018 by Ateiva (Now called Lucid) as a security consultant.
They wanted advice on how to secure their cars from people like me.  Among
other things, I told Peter Rawlins that the best way to secure their cars
was to open them up.  If people can get EASY access to service and
diagnostic info, and quell curiosity, they are much less likely to engage
in determined hacking to break in.   I got the feeling they didn't take my
advice too seriously.  It's IMPOSSIBLE to secure something where the
attacker has unlimited physical access, all you can do is slow them down
and piss them off!  (I did give them other advice too)
