I would be interested to know how they calculate driving cost. What assumptions have they made about fuel economy and depreciation of the vehicle? I agree with SEA-Flyer that the SEA-GEG drive cost seems very out of line with reality.</font>
If you set gasoline cost to zero on the maps you see that driving round-trip Austin - Dallas (400 miles) costs $80.
Raising gas cost to $2.00 per gallon will increase indicated driving cost to $100.
Therefore, Dream Maps is based upon 20 cents per mile for depreciation and maintenance, and 40 miles / gallon fuel economy.
