I’ve tested a few dash cams in the last year (for example the Swann DriveEye and the Papago GOSAFE 520) and I’ve been impressed. Even if you’re not planning to capture the next meteor screaming over your town and shattering windows for miles around, it’s a great hedge against fraudulent insurance claims against you and terrific documentation for any road travel incidents you might have.

But as with all technology, while there’s a lot of value in point application, when the point data is aggregated and treated as Big Data, amazing opportunities and insights emerge … which is exactly what comes from turning your iPhone into an ultra-sophisticated dash cam with the Nexar app.
