You're absolutely right about the cell phone thing; I use my phone for things like reading distant signs (while mostly stationary) and reading restaurant menus that are posted on the wall (I probably have taken hundreds of such pictures). Using the phone to watch videos or keep up with whiteboard exercises would be challenging without a tripod to hold the phone and probably a custom camera app that lets you quickly pan a live zoomed image. I've always found it hard to quickly locate distant objects in my ocutech though given the limited FOV, and doing it at driving speed must require a lot of deliberate practice.
