Increased Resolution of Typical Traffic Graphs
For those of us trying to avoid traffic, a "congestion timeline" would be very valuable. Google already has a "Typical traffic" slider to illustrate which roads are usually the worst, but it doesn't show a timeline. Here's a user interface prototype I've made to illustrate this idea.
As the user scrolls and zooms to view different areas, the graphs should automatically update, with smooth "ease in" bezier animations.
EDIT: as of June 2017, Google now provides graphs to indicate how long a specific trip might take depending on the time of driving (i.e. longer during rush hour, etc)
I've annotated a screenshot of this new feature below, where I indicate the need for more granularity, as well as the ability to more fully explore the dataset. (all 24 hours of the day, instead of the nearest 3 hours)

Snapshot of ideas
I look forward to publishing more feature requests for Google Maps and mapping technologies in general. Here's a collapsed screenshot of my feature requests ( [fr] ) for Google Maps.
