Get distracted? I mean, are you American? Have you ever looked around you in traffic? Look at all these billboards and bullshit and tell me about distraction. If you are on a mission you do not open your social media. People do so due to boredom, I guess. The sensible thing to do is... stop using social media.

Aside from that, let us assume you won't stop with that (after all, it is free!). Smartphones have a driving mode which you can set, setting them on DnD. I take my smartphone out of my pocket when I wait before a traffic light, and that works, but I only do so when I need to and what I certainly do not need to do at that point is have a look at Facebook or Twitter. I also don't have Bluetooth on 24/7 on my smartphone (one reason being tracking concerns). On a Pebble watch, I can put this off. Sadly a software killswitch, but better than nothing.
