Hmmm... I don't think so. The Speedster was a lightweight, simple car with a potent 4-cam engine. The New F-1 is large, heavy, and reasonably complex in what it could do (e.g. its metering and modes).
Not larger than a Nikon F2 (another really great camera), not heavier than it, and as for complexity, i'd say it's not complex. Switching between manual and aperture-priority modes, and knowing in which mode you are, is highly intuitive, since the whole display changes between modes. How to set aperture-priority? Easy, set the shutter speed to "A" (automatic). How to set shutter-priority mode? Easy, set the aperture to "A" (automatic). Of course, for the latter you need to attach the motor or winder, and for knowing this you need to read the manual. As for the metering, again, if you have not read the manual you won't know what metering mode you are in, since it depends from the focusing screen.
In fact, besides the switchable metering patterns and the special need for motor for shutter-priority AE, everything is really simple. Removing and re-attaching the viewfinders or screens, for example, is simpler than in the F2. Changing shutter speed and aperture is the same as in all cameras that follow the Spotmatic ergonomics. The stop-down lever is also very intuitive to use. Battery change surely is easy, unlike (say) a Nikkormat EL.
Now, i have been playing games, since the real competitor of the F-1N is the Nikon F3, which indeed is a smaller and lighter camera. And as easy to operate.
