TLDR: Service Center employee took the Tesla out for a test drive to ensure repair was completed properly, ran through a 4 way stop, was T-boned by an Audi. Audi driver in hospital, Tesla shipping a new Tesla to the owner.
Audi driver’s really the one who got screwed here. He did nothing wrong and he’s in the hospital.
The Audi Driver should own the service center when he heals up.
