Open an oven, but not entirely, just a few inches, the air that is forced out from the oven through the narrow opening will burn your face instantly. Open it entirely, and whilst hot it's still far less heat. My point being, that the streets could act like canals for the heat, concnetrating the heat. Just a guess, perhaps mathematically irrelevant. Fire has many 'exceptions', and can be influenced my many different variables and situations.
