The very first thing I did on getting my recumbent tricycle was to swap my cleat pedals in (rather than the ones it came with, with a plastic foot cage), and I shudder to imagine the result of feet falling to the road at 30km/h.

Of velomobiles, remember that they normally have foot wells; if uncovered, the harm of feet falling will still be reduced, but not absent.
