I thought the whole idea of the car was to be able to perpendicular park on urban streets. I was surprised that they are not commonly used that way, and they get worse mileage than my four-door, huge trunk, safe at 80 MPH Toyota Echo.
Works for 1st Gen SmartForTwo, 98.4" long. Current model is 8 inches longer, puts the load over legal width by four inches, subject to "wide load" signage and possibly buying permits, but not escort service. Not that we worry much about where we are legal on width or length.
