Am I the only one who really doesn't like this idea? The more I think
about it, the less I like it. It feels like putting a plug instead of
getting a new pair of tires. I'm surprised at my own reaction, since
it is not going to affect me all that much, and so I will let it go
if others like it (but it feels like a bandaid to me, and once it's in,
we won't be able to remove it).
