This is a humorously-titled reflection after ASC 2018, aimed at figuring out why our car seemingly does worse compared to the competition. Hopefully we can identify areas of improvement, knowing that these are obtainable baselines that other teams are able to meet.

300 miles - 242 miles = 58 miles |
Where are the other 58 miles going?
Note: We were targeting a cruise speed of 60 km/h (37 mph), but App State averaged a minimum of 42 mph assuming they started at 9 am and travelled 210 miles by 2 pm. We found that going 6 mph faster significantly increased our current draw so it would be unlikely that we would make 242 miles with 40+ mph.
