Tesla is famous for publishing the logs. The owner should be aware of this before making claims. It would have been prudent to keep this quiet till Tesla had a chance to respond. Now if the logs prove it was driver error Tesla will publish the logs and all this outrage would be over nothing. On the other hand if this was an error in Tesla's system it is in Tesla's best interest to be transparent and publish the logs and an explanation on how it intends to fix this.
Either way a public outrage was not required unless the owner wanted to ensure he got a new car even if it was the driver's fault. By claiming ""I don't' know if they're going to acknowledge if it was their fault," Puzant said.", the owner wanted to cast doubt on Tesla's integrity and also give himself an "out" if Tesla determined it was driver's fault.
