Since the freeways are no longer congested, I was able to conduct a fun and simple experiment throughout the last month or so. I set the cruise control going to and from work at 65 mph and recorded the average energy and the temperature for each trip. It's not a controlled experiment by any stretch as the freeways here in SoCal are mostly flat, but not perfectly flat. I made sure to have data points for going to and from work when it's warm and when it's colder so that the data is not skewed. Yes, that I meant that I went to work at and coming home at different times of day on purpose just to capture data from all temperature ranges. Trips where I had to cancel the cruise control for any reasons were discarded. Also trips shorter than 10 continuous miles were discarded. Most data points recorded were from trips in excess of 30 continuous miles since my total commute is 45 miles each way. I also did one for 60 mph to compare, so I'll chart that later. Enjoy.
