This analogy is off.
Cars are driven on roads with other drivers and often non-drivers. Road conditions -- including inclement weather, chemical spills, etc -- contribute to car accidents. Other drivers contribute to and outright cause accidents. Non-drivers do likewise. Furthermore, even if this weren't so, even if the chances of a car accident were much lower than they really are, the likelihood of any given accident causing death or debilitating injury is high enough that anyone with a rudimentary grasp of expected outcomes would wear a seat belt all the time.
Whereas your pocket knife is almost always you, the knife, and whatever you're cutting. When you do use it in those rare circumstances where conditions are unfavourable for the use of a pocket knife, you can almost always mitigate the risks of injury by using the knife safely. And a lock doesn't stop any of the really common injuries associated with accidental impacts with passers by, slipping with the blade, etc. Closing the knife on your hand means YOU fucked up. And even though the chances of slipping and cutting yourself with a knife are much higher than you just plowing into a building with your car (unless you make it a habit to drive totally out of your mind drunk) the chances of the injury being life threatening are pretty damned low.
In short, the comparison is really flawed.
For most of what you use a pocket knife for, you don't need a locking blade. You're way better off just being careful and remembering that you're using a pocket knife and not a scimitar.
Or, let me put this another way: You know how my grandfather managed to not slash himself terribly with his non locking knife? He used it properly. And doing that still works to this very day. It's why you can safely use non-locking SAKs, the blades from non-locking multitools, and of course the good old fashioned non-locking knife. You remember that you're not fighting fucking pirates with the thing, but whittling or opening boxes.
Because if you're doing something that absolutely requires that you exert pressure on the spine of your pocket knife, you're using the wrong tool or you're using it wrong.
