Dive Bar Rigs

While in the matrix using a rented rig, either from the dive bar or else where, the amount of time you have left on your rental should display somewhere, maybe when you type "'Status", to help prevent you being abruptly kicked out.

Yeah, this is a good idea. Or as like a little glowing timer at the start of room descriptions, to portray it always being in your character's field of view (after all, you're using a cheap rented rig, you dont get the privilege of not having annoying timers in your face)
