I just don’t see it as a convenience.

Sorry. What are the benefits that exceed the potential hazards?

You can start a car by pushing a button, I can start it by turning a key. I don’t see the big time saver. You still need the fob/key and when I want to exit the car. I am unable to remove the key if the car is not in park and I lock the car by using the key fob.

I keep my fob on my belt and it doesn’t get lost.

I keep my fob on my belt so no way I can lock my keys in the car!

Keys dropped in drain:

Nobody is clamoring to bring back the car key. Though if you really are a key-head, you can still extract a traditional metal key from your fob (people are always amazed when I show them this).

Eventually, the technology will get to the point where people can start their cars with their retinas or fingerprints - much like they do with cell phones. Keys will soon be an anachronism. But a few will still have them much like people still get those classic "retro" rotary phones.
