I like the fact that Google search always warns, and the warning is not obtrusive yet it very obvious. I'd be completely fine with that even for something that should be obvious - Google of all companies should understand that obvious isn't always.

But the thing that gets me is they've solved this exact problem with Search already, and it's far, fr less important there than it is with Maps - extra mouse clicks are not the same as driving across town. Apparently no one in their Cambridge office goes to Brighton. . .
