One of my favorite moments was seeing the cab driver take a bathroom break. I don't remember seeing that before on any other race.
Louie and Michael in Singapore?
I didn't remember it, so I re-watched it, and Louie & Michael took their bags with them up to the Fast Forward. When they came back down, they didn't see the taxi driver and they assumed that he went to use the restroom, but there's no clear footage of him going into one or coming from one. He just jogs back from inside the complex.
With Charlie & Rachel, their taxi driver left them in the cab and we see him coming out of the restroom.
The closest thing that I can remember to three straight NELs is three NELs in four episodes during TAR5. I especially remember Kevin & Drew mentioning it back then.
