When choosing a route, I would like to see a degree of confidence that I will arrive at the time specified. More of them than not, I arrive at my destination several minutes after the original estimate due to building traffic, getting stuck at lights, etc. This especially occurs during rush hour traffic. If the app offered a level of confidence based on the proposed routes then I would feel like I have more control over my route. This could be represented as a % confidence based on conditions and aggregated data from users along that route or ever a color code (green, yellow and red) for which route will most likely arrive at the specified time.
