>Instead they should show the rate money is being spent based on the current price per gallon. That would be incredibly complex. You'd have to have internet connectivity and a central server to download that data. Average where? Average in Hawaii or Kansas? Gas prices change every day, too. So the solution would to be have a GPS on when you fill up your tank and record a timestamp and average price for the current area where the tank was filled up. I'm not convinced that the benefit would be worth the work and privacy implications and would only be available on the highest end cars. It could be argued people spending their money on a higher end car are less worried about how much they are spending on transportation so less worried about how much they are spending on gas... I'm also not convinced anyone would pay attention to that number or if they did understand how to improve it without clear instructions. It is just another number being displayed. They would have to be paying really close attention to notice a pattern at all and if they are paying so much attention I'm arguing they aren't paying attention to the road.
