content: to be fair driving the same 16 mile loop 35 times in a 95 degree car sounds like some type of hell, especially as they likely were running nothing electronic and a little weight as possible so just the two of them talking for a day straight the speed was probably picked for efficiency so no speeding up or slowing down just set the cruise and go, wonder if they could use autopilot probably not as more computing is more electricity so less distance. Just sitting there and going around the same loop every ~30 minutes (guessing at speed here) over and over again. Edit just did the math on the time and distance they averaged 23.58 mph so a 16 mile loop would take 41 minutes
