I'm interested to know if you considered this and have a different opinion.

A simple thought experiment: while cruising, close your eyes for ten seconds. What happens?
If you do this with a car, you're probably no longer driving when you open your eyes again. If you're on the highway and are unlucky, you never open your eyes again. If you're luckier, you've come to a stop by plowing into something. It's unlikely you're still cruising.
If you do this with an airplane, you're almost certainly still flying along fine. You may be off altitude or heading some, your airspeed may be getting into dangerous territory, but you're generally fine, and haven't suffered anything that can't be immediately fixed. There are things that can go wrong in those ten seconds to kill you, like a mid-air collision, but they're rare and not something you can avoid with confidence even with your eyes open.
This short-term ease is more than made up for with long-term planning difficulty. I can go hop in my car right now and set off for Los Angeles and be pretty sure I'll arrive safe and sound in a few days. Doing the same with an airplane (if I had one capable of making the flight, and the appropriate license) would require substantial advance planning, otherwise I could easily find myself killed by weather or lack of fuel.
In short: that pilots use HUDs is not as informative to their safety in cars as one might think.
You can operate Google Glass hands-free.
I know it can be operated hands free but you still have a potentially distracting display.
However, if I ran a secured workplace, I'd really think twice about letting my employees or hell, anyone, show up on premises with one. The ability to surreptitiously record everything you see is pretty hard to counter, security-wise... especially when it can save to local disk and transmit later when clear signal is available.
I live in Long Beach, where TED is held, and I had personal experience with someone using Google Glasses while driving during this years event - I was on my motorcycle a few blocks from the convention center, and I finally pulled over (in heavy traffic) and waited for him to get well away from me before I entered traffic again.
I hope these things are banned from use while driving - it's bad enough trying to stay alive on the roads as it is.
