CallMe Prism-i LCD Display Conveys Your Phone Number to Other Drivers – But Why?

We're at somewhat of a loss as far as this seemingly curious gadget is
concerned as we cannot quite fathom why you would want an LCD display
stuck to the inside of your car's rear window displaying your phone
number - unless, of course, you've looked in the mirror and caught the
eye of a particularly fine blonde behind (then, and only then, it would
make total sense).

Billed as an 'artificial intelligence driving monitoring system' (though
this may be down to the peculiarities of a machine based translation
from Korean into English), the CallMe Prism-I can store up to ten phone
numbers any of which can be displayed on the scrolling 13 digit LCD
screen which, thanks to an integrated solar sensor, will automatically
back light the display (in either blue, sky blue or green) in low
lighting situations - and, from what we can gather, the solar panel also
seems to serve to power the device during daylight hours with batteries
acting as backup.

It’ll also randomly conjure lotto numbers. Which is nice.

Perhaps we've missing something here (and I'm sure we must be), but
unless this has been specifically designed as a 'pulling' gadget we
really don't get it. Perhaps a kindly reader who happens to be fluent in
Korean could set our minds at rest as to what exact purpose this curious
device is supposed to serve lest we end up not sleeping at night.

The CallMe Prism-I retails for around $26 / pound sterling13 / 17.
