Mostly the complaint is just time. The 20 minutes at breakfast time and the 30 minute difference of getting home late are in valuable time slots. It's uncomfortable to shift those around. I've been trying to get our family to go car free for a few years. I've even pushed to move so that we are closer to work and so the commute is less of a burden. She isn't interested in going all the way, she isn't a biker at all really. So she tolerates it as a hobby for me. We get along very well and there aren't other underlying issues. She is willing to work with me, I just can't quite get more days.
I guess that is the problem with a longer bike commute. The time commitment, ... which is awesome for having more time to ride but difficult to carve out that time.
Concerning bikes banned at work: I work at an industrial plant. A new plant manager recently started and feels like it is unsafe to ride onsite. The offices are located in the center of the plant, I used to ride up to my office. They installed turnstyles with badge entry at each gate except for the main gate that is one mile from my office. So I can't get my bike in through the turnstyle, I have to come in the main gate and walk to my office. I have convinced them to install weather proof bike lockers, that is just taking a bit of time. My current commuter bike is a shiny CAAD10 and i'm not willing to just lock it up outside because there is high risk of theft.
