Why would they need to reach me? If they really need to, they can ping the OnStar system, or whatever proprietary system is built into basically every new vehicle. This is assuming they don't add their own tracking system after taking delivery. A company the size of Hertz can absolutely know where every car they own is at any point in time. It doesn't mean that every employee can just look it up for fun but the info is available to those who need it.
