Miami tried this, made tolls $7+, it did nothing. And because they put up barriers between the express (toll) lanes and regular lanes, when someone got in an accident in the express lanes, it was FAR slower than the regular lane. The mentality was/is '$7, well its worth it because I can't sit in traffic'
Came here to mention this exact thing -- you don't even have to be an attending, my wife and I have this loan through a different company, and she is still a resident. We had banks fighting over our mortgage. No money down, no PMI, and they portfolio the loan instead of selling it right away like a standard mortgage. We live in a Detroit suburb.
The largest issue I've run into with respect to issue tracking is making it accessible and easy to use/understand for the entire team. Non-technical team members don't have GH accounts, they don't know if what they are seeing is a bug, they don't know if its already been reported (because they don't understand the root cause), always seem to be afraid of doing it wrong.
Further, a tool that tracks the resolution of issues into a simple to read 'This was just deployed' or some kind of digest would be insanely useful. It's not an easy task, but so often someone is waiting for a fix, or waiting for a feature, and then gets upset or something gets overlooked because they didn't know the feature/bug was deployed.
Something simple, with an app-store style approach to customization could be really handy.
