You would not be able to keep your glider in a bonding pouch for a day and a half. Gliders must have time to exercise, have access to water and eat at night, even if it is in a small travel cage.
Bonding pouches should never be worn by front seat riders - driver or passenger. Should your vehicle be involved in an accident the same air bags that would help prevent injuries to front seat riders would most likely be lethal for gliders worn on the rider in a bonding pouch.
If you cannot get a travel cage and decide to leave your glider at home, it will be fine with out being played with for a day as long as you have someone reliable to put your glider's regular food into the cage in the evening and take out the plate and leftovers in the morning.
