Absolutely not. The cars should launch perfect, not just as good as humans. If you have any other human operated machine and replace it with an automatic one that sometimes kill humans, does it matter if it does it less often than the human operated one? Absolutely not - a machine cannot have an operating mode where death is possible. Look at Therac radiotherapy machines - they surely saved hundreds if not thousands of lives from cancer - but they had an operating mode that would kill the patient. Does it matter than a manually operated radiotherapy machine would most likely kill more people due to operator errors? Again - absolutely not.
