I just rented a Budget Camry last week for a day, and have to rent a Corolla for a week in the near future, but I doubt the system is in either model.
They seem to be installed more in what are called, speciality vehicles (Lincoln Town Cars, Ford Expeditions, Ford F150 pick-ups, Higher priced vehicles).
So, if you stay with the smaller, more common vehicles, I don't think there's much to worry about.
I found some interesting comments from some of the Rental company bosses about the systems that are installed on their rental vehicles:
