Is there a way to report suspected erroneous entries?
Is there a way to weed-out the bad entries? I see people are too ignorant or careless and you end with erroneous numbers that alter that averages and ranges?
Potential feature suggestion: designate users as "trusted". As you come across users that appear to be reliable in their entries, can flag them and get MPG data from all of your trusted sources. Could also use it to narrow down the cars you want to compare to.
I've not found a way to correct erroneous data entry, such as the last time I fueled-up, my phone mangled the data, so now fuelly shows me getting. 4.1 mpg.
Maybe the best way to deal with this is close your account and start over with a new one.
