And she's back! And I feel slightly judged for my fashion choices (only at home, of course...)
Totally understand, and that makes sense with needing to automate the mileage process. For my company, I don't think we're at a point where that's as big of an issue, and people are okay with how things are. Not saying that's a good reason to avoid Drive, but we're weighing that benefit alongside cost, the time it'll take to train our employees, and other factors. I assume by your tone that it's been working well? I don't think that we necessary need to see X% more efficiency or anything like that, but we want to make sure the benefits are worth the cost.
As for the first issue you listed, as far as I know, that's only the case on Concur's desktop version. We talked with a Senior Solutions Consultant at Concur and she said there is a tag for 'Auto-Tracked' when approvers view reports in the mobile app. She even gave me this nifty screenshot, too:
About inclusion on the desktop version, she said, "I anticipate the ability to view on concursolutions.com is a roadmap item."
But I agree that the second issue is one we're eyeing carefully. If they were to just implement some admin controls that could allow or disallow users to edit the date and distance, that would be a huge item in our 'Pro' column.
Overall, we like the idea of Drive, but the untested nature combined with some other factors internally are giving us pause at the moment. We're currently in the beginning stages of a process to replace our accounting system, re-do our general ledger format, and potentially replace other large systems we currently use, so this has been put on a medium-back burner for now.
Thankful for your insight, though! It's nice to have friends in high places 🙂
Everybody loves shiny new toys 
I would love to just do a tiny set of instructions, but I'm not sure how it would fair with our user base. Just a question: How would you describe the demographics of your Concur users? More tech savvy and quick to learn new things?
For us, we have everyone from hip young people who are quick to learn new tech, to baby boomers who are less than technologically literate, to elderly individuals who just learned how to Facebook. Not all use Concur, but I've had more than one hour-plus-long conversation helping to walk some of our employees through some very basic things. So when we roll out any changes, we try to communicate thoroughly and often so everyone gets it... hopefully!
