Many of these have similar risk cost vs. risk reward tradeoffs. Climate control helps keep you focused (I know I have a hard time focusing on the road when it's 40F in my car) and cruise control helps keep you predictable to other drivers.
Bluetooth integration assumes people are going to use their phones either way, and thus handsfree is the safer choice. GPS informs drivers in advance so they don't have to swerve across seven lanes of traffic to make their exit.
My point is, what problem does Glass solve that makes it worth the risk?
If future iterations of Glass are able to incorporate existing dash functions, thus making them safer to access by not having to take one's eyes off the road, then the benefits are obvious.
