Reply #2: Is it worth the expense and material waste to outfit millions of cars with float technology,

[Rabrrrrrr]

just because a couple go in the water each year?

No, not really.

It's a good idea, but not worth the cost.

There were some cars made in the 1950s (maybe 60s?) that are amphibious, and there's a worldwide organization of owners of them. I can't remember the name of the cars, but I saw a little snippet of it on TV once, at one of their annual gatherings.
