The competition won't do anything (for a while anyway). (No one would have been able to guess that this was your "main interest".)
The Garmin Varia is the same price. The distinctive advantage the Trek device has is the lateral position but that's only viewable on the phone app. I think most of the people using these are not using phones. It's not clear how useful this will be in the real world (most passes don't include full lane changes). It's not clear that the Trek device is better than the Varia.
Yes, this. It almost seems as if Trek got this to market, and then realized that it adds nothing beyond Varia's capabilities -- so they fudged the detection distance (according to the first few brief reviews) and added a phone app that will be used by very few customers. (I mean, who buys a $200 radar tail light when they don't already own a head unit?)
