Texting and driving are a dangerous combination – and Don’t Text Me 
deserves some measure of praise for attempting to address it. Notifying contacts that you’re driving or working (or otherwise unavailable) is an easy process, but it overlooks a couple of major issues. While it’s easy to ask friends not to ping you, it’s ultimately their choice — and if they do, you’ll receive those texts without any interruption. Just as importantly, if you’re frequently in and out of the car (or in class or meetings) and use this app regularly, friends may get frustrated with the frequency of the messages.

For every 6 seconds a driver spends texting, 4.6 of those seconds are with their eyes off the road, which makes texting the most dangerous cell phone activity anyone can engage in while operating a 5,000 pound piece of steel and glass. This activity produces 6,000 highway deaths a year and that number is rising.
I decided to do something about it after my three year old daughter was nearly run down right in front of me by a texting driver in Seattle last fall. Instead of an expensive shackle that locks down phones and alienates the user (especially teens) I built a tool that is a simple app for smartphones – low cost, no recurring fees. I think if we can empower the individual then change will come to our highways now and not just our laws.
