Here's a historic form of transportation peculiar to small sections of a few American cities, primarily for tourists. This Leica T/18-56 image shows the limits of the JPEG engine when the weather, skies, and lighting are wet, cloudy, and dull. Pixel smear is visible at 100 percent view, particularly on the trees, and this at ISO 100. (note that the small segment of sky at top center was flood-filled from a saved pattern.) f5.6, 1/125, ISO 100.
