He came fairly close, honestly. "I'm going to do my best not to die, but I'm excited about this tech" is recognizing, and accepting that death is a possibility as a result of Tesla's self driving process.
There's risk of dying every time I get behind the wheel of any car. There's no benefit to pretending real risk doesn't exist in any given scenario. I'm confident that I can be attentive and cautious enough using this tech to keep the risk similar to what it would be just driving normally.
