Final answer:
The driving instructor did not call David anything; the narratives provided do not show a driving instructor addressing David. Instead, one refers to a 'Boy' being asked about a golf teacher, and the other involves Peter reflecting on a stereotype associated with elderly drivers.
Step-by-step explanation:
It appears that there are two separate stories being mentioned. In the first story, the driving instructor does not call David anything; rather, it mentions someone addressed as "Boy" being asked about the whereabouts of a golf teacher. In the second narrative, Peter encounters a slow driver and thinks to himself about the stereotype of "DWE," driving while elderly, but again, there is no direct connection to a driving instructor calling David by any name.
