When picking up my Budget rental at the Ft. Myers airport (RSW), I allowed myself to be talked into taking a 2009 Prius (no extra charge) instead of the unknown "compact" that I'd asked for.
It had a backup camera which displayed in the large info LCD screen in the console, and whenever the car was put in reverse it emitted a constant "beep beep" (audible only inside the car, I hope) like a piece of construction equipment.
Do they all come with the camera, and do they all beep in reverse, or is that something Budget added on?
