Really? A plug for a paid app? I feel like you're trolling me slashdot. The only possible reason I can see to post this is as prologue to an American lawsuit the first time a user dies using this app on a highway.
On a similar note, perhaps a story about the lawsuit against Strava would be more appropriate? A free cycling gps app that has the ability to ghost race yourself, your friends, and strangers was sued for negligence when a user broke the laws of the road trying to win a virtual race and was killed in traffic. See what I did there? A piece of free software, most people own a bicycle, tricky legal questions arising from technology, more than just an add.
But hey, what do I know? I'm no Samzenpus!
