In which book does a man start whistling a tune, only to discover moments later it is playing on the radio? (and thereby showing passive telepathy)

Clues:

• It could be very well be a book by Philip K. Dick, but probably not the blockbuster movie ones, but the ones that are about the detachment of a lonely anti-hero. But he's not a certainty.


• It's is a novel written between 1950-1980, certainly.


• The relevant scene happens in first or second chapter, the beginning of the book in any case: Two men sit in a car. One whistles or hums a song. The other, perhaps the driver, turns on the radio and the same song is playing there. The ensuing dialog is something like:
  
  
  
  • "The odds of that happening must be rare."
  
  
  • "This is not the first time this happened to me / Happens to me a lot"
  
  
  • "Maybe it means you're passively reading the minds of every listener around you"
