It'd be awesome to be able to see colored lines on the dashboard, both in aggregate and for individual trips, showing speed instead of MPG. It'd be great to have a scale for different speeds and color the lines accordingly. This could be another selectable graph mode in the web dashboard.
Thanks so much for sharing, and welcome to the Automatic community. While we don't have any current plans for such a feature, I think it's a wonderful idea and I'm bringing it up with our team to be considered for future releases.
Should you have any other ideas or any questions in the future, please don't hesitate to share them with us.
