Hey Sha -- I can't speak for the rest of your cities, but Tampa, FL is VERY wrong. I drug the end point to downtown St. Petersburg and the times given appear to be almost double what it truly takes to commute, over a certain threshold. Under 20 minutes seems to be accurate, but it starts trending towards 30, 40, 60 minutes too quickly.

I'll tell you what, though -- great UX and visualization. Very plain to read and utilize the slider functionality. I suggest modifying the legend to be more explicit about what the color bands mean -- perhaps labeling each color, for instance.
