One data-heavy but useful addition to maps like these would be incorporation of time-of-day and day-of-week. The distance you can travel on Monday morning at 9am differs greatly from the distance you can travel on Thursday at 3am, for example. I've long thought it'd be useful to have that kind of information incorporated into gas station / charge station maps. IE: from a given position, how long will it take to travel to the nearest fillup station that will be open when I get there.
