Discussing cross with Laspisas and how Dusek was getting upset at Dave's answers. People have different ways of going places, of doing things. Laspisas chose a different way than Detective Holmes drove to Glamis. Route is not unusual, highway has hazards.
What would Neal Westerfield know about the route 5 years ago? He was 13--do you remember the drives your parents took when you were on vacation? How about what you were doing five years ago, precisely, under oath, and don't slip!
Two reasonable interpretations? There are 5 reasonable interpretations, but the one the DA wants you to believe is that this is suspicious, unreasonable. If it was sneaky or unreasonable, where's the body? Why wasn't the body there? According to the argument, that would have been a perfect place to dump a body.
