Podfish, you raise good points. I understand that the comparison between driving and owning a gun is not perfect; but I think there is enough commonality to make the comparison useful. And I get that it would not be easy to repeal the second amendment. It is difficult to change the constitution.
But there is precedent. The article that enacted prohibition was repealed by what is probably the simplest amendment to the constitution. In a similar way I think the focus could be an amendment that would say, 'The second amendment to the constitution is hereby repealed.' And leave it at that.
This would change the conversation and allow for a more nuanced discussion. I don't view such a repeal as anti-gun; rather I think of it as anti-gun rights.
It's a long shot (joke intended), but stranger things have happened.
