Yeah, I'm not quite sure what you're asking about here. I'm guessing you'd like Fuelly to calculate your highway vs. city mileage?
Maybe if we had a way for people to report what percentage of a tank was used for what type of driving we could show some sort of statistics about highway versus city, but I think even that would be fairly wild guessing by all parties.
yea you would have to put in what percentage did you drive city? and and then it would put the rest as highway. This would not be too bad if you did all city one time and then went on along trip. Normaly I would have to say 90% city 10% highway. It could be option to use for us hard core Fuelly folks! LOL!
We've talked about including a slider on the fuel-up page that lets you estimate what percentage of city vs. highway driving you think you had for the last tank. I do think it'd be fun to start accumulating that data, but I don't think it's going to be very accurate. Which means a city/highway slider (and any stats that come from that input) could end up being frustrating for people who want precision.
yeah, I really think it's too difficult to differentiate between city and highway driving - particularly if you're in an area like Houston where you do a lot of city driving on the highway... the best you could do would assign a "feel" to your driving.
