I just think that, considering the number of miles driven in the US and the poor quality of your average driver, the number of deaths is surprisingly low. This is probably at least partially due to the safety regulations that have made cars a helluva lot less of a killbox than they used to be.
If you don't recognize that while driving you have at least some control over your own safety I don't know what to say. Total control? Of course not. Can you not speed, not read HN while eating a burger, not blow through traffic lights without looking? Of course you can.
It would be like arguing against buses because a bus driver can wig out and drive through a cliffside guardrail and there's nothing you can do about it.
