When riding in a car someone else is driving, the anxiety, fear, or hyper criticality of everything the driver does and/or on the road.

Can lead to becoming a Back Seat Driver, or Passenger Seat Tourettes Syndrome.
Passenger: slight vocalization of concern going around a corner
Driver: Are you okay?
Passenger: Yeah it's just a little Passenger Syndrome.

Driver a quarter mile ahead: taps brakes
Passenger: OH MY GOD SLOW DOWN THEY'RE STOPPING!
Driver: Geez relax, your Passenger Syndrome is insufferable today.

When you have to decide between sitting multiple cars usually each having 1-2 people already, meaning that you are showing "more" respect to the car that you wish to sit in. Usually solved simply but can be thought about rather seriously.
Mike and Tony were both going to Caribou Coffee in their cars with no passengers, they were leaving from my place, so I would sit with Mike and say see ya there Tony to balance the Passenger Respect, possibly giving disrespect.
