There are any number of reasons the traffic server might return a
redirect.  For example, suppose the main traffic server is overloaded
and wants to offload the processing of this request to another server
(say in a different datacenter) temporarily.

Even though the in-car navigation unit has a user interface, it's
definitely wrong to make the user confirm this redirect.  The user is
busy driving!
