How do drive time maps save fuel?
An Internet-based map store put out a press release offering custom drive time maps. The selling point: they save gas. There’s no real explanation of how they’d be used for that purpose and I can’t think of any.
Update 3:26 pm: Based on the comments below I realize I didn’t define drive time maps. That was an error. Here’s the definition, a fine one, from the vendor of the maps in question: “Highlights drive time range limits.” Such maps define the boundary of how far a driver can go from a specified point in a specified time. The vendor suggests 5, 15, 30, 45 and hour ranges, but will accept any value you choose.
