I explain it like this. From downtown Los Angeles, drive to Las Vegas (5 hours) and San Diego (2 hours).

But in 30 minute increments: 30 minutes heading toward Las Vegas, then 30 minute heading toward San Diego.

They'll run out of gas and be in the middle of nowhere. (Kind of like what happens when you multitask as a software developer)
