I don't text-drive!
But text-walk I do an awful lot & I realize this could be equally dangerous when done outdoors (read: roads). It so figures that big brother G too is pretty worried over the gory implications of text-walking and started to ideate-on (& patent...) some potential solutions that'll likely result in a new app which could make stuff like alertness, caution & looking-up pretty much passe'
An app that can save me from walking into trouble? - I'm sold!
