We are not liable for...
Tesla is acting like a typical software company. I have commented several times in the past that my personal opinion is autonomous vehicles are going to run into problems because the manufactures are not going to want to accept liability -- they want to act like software companies instead of vehicle manufactures. Given that the autonomous vehicle community is spinning the tech as something that will save consumers live, and money on insurance, I am guessing they have no intentions of every accepting liability -- the autonomous car is/will be perfect in their eyes so no need to look to them for problems.
If Telsa accepts liability for anything accident related, they open the door a little. Every time the door is inched open an attorney, or group of attorneys, will poke their heads in and say hello. They likely prefer the strategy of keeping the door locked at the moment - can't say I blame them.
Still, much work must be done in regards to changing liability laws for companies to be off the hook. If they do succeed, it will be you and I to blame for everything. We used the wrong soap when we washed the car therefore it left a film on the sensor; the tires were not balanced properly therefore... And we thought dealing with vehicle warranty issues were bad.
