I have advocated in the past that the DB allow cross-sections of geography, route time, and climate, so that people wondering what they will get in a particular car can better match themselves to other's experience.

To a variable extent, I annotate my tanks with techniques I use, routes driven, and typical speeds compared to the limit. This is free text, and would have to be read rather than sorted, but if more of us do this consistently, then lookers with some motivation would be able to more closely match themselves to their own kind, or realize what is involved in better results.

Many hybrid drivers on this forum may drive differently than average Joe LeadFoot, but that does not make it any less. For all I know, as FE gauges become more common, coasting, anticipating, driving slower, gliding etc will become the norm rather than the exception.
