In Canada your landlord is required to pay back your deposit with interest, so if you gave them a $1000 deposit and stayed for 10 years and interest is at 5% they would be giving you back about $1600.
Very few actually do this and most of the time interest is so low nobody bothers to fight for it.
Entirely self interested opinion, but I think older fuel-efficient cars ought to qualify for hov too - driving an efficient car that already exists is definitely better for the environment than junking it for a new giant electric SUV/truck.
