Yeah that is certainly the danger of my oversharing here: you can see how fast I drive. It was strictly for scientific purposes I assure you ;-)very nice presentation and reinforces my belief that cruise control has limited benefits after seeing the speed on your logs varying from 54 to 82 MPH
I do use cruise control a lot to soften my lead foot a bit. I'd like to do a more scientific study though of how using cruise control on a given stretch of road uses less or more power. I am sure theories are abound on this. I think that it probably hurts on hilly areas since the car can be quite zealous in maintaining speed up big hills, and perhaps not aggressive enough using the downhill to your advantage.
I am thinking in future versions of the site you can "name" trips and also "tag" trips. Tags would be more like categories, like "to work" or "from work", or "cruise control" or "no cruise control". This would make it easier to compare trips. Naming trips like "Charging test" or "incomplete log" or "long range test" would make it easier to fidn the trips in the long list of trips.
