Over engineering? ... brings back memories of the info-mecial ads on TV of the whizz- bang egg cracker device.. "No more messy fingers!"
Umm, ...very rarely do I ever get messy fingers when cracking an egg, and at a cost of $52 for a mechanical tool to 'aid' the process of removing the shell from an egg, ???..
I think I will prefer to glance in my mirrors when necessary, drop my eyes to the GPS if needed, and 'Sarah' can either call me later, or I will call her back when I have finished touring for the day, there is a very good reason why I removed the MP3 disk player/radio from my bike many months ago.
