Sincere question -- is your concern looking away from the road, or looking down at your wrist? I take glances out of the direct line of my travel all the time, to check lanes around me, look at the speedometer, tachometer, fuel level, etc.
I do find it surprising that the pictured model would wear it on the right arm, though, since it's much easier to take your left hand off of the handlebar -- you don't tend to need to use the clutch when cruising on a highway, whereas (unless you have a throttle lock) your right hand will typically stay on the bar.
I do think motorcycle safety is important, but your reaction seems a little overboard to me. Having navigation on a small screen on my wrist seems like a relatively nice perk.
