Benefits of trikes are small, and simply don't outweigh the drawbacks when speed goes up - along with their dynamic instability .

The Sinclair cg moves forward drastically with the brakes on. It requires vigorous hiking maneuvers by the rider in an emergency. These are precluded by the new canopy.
My velomobile has 25% of the weight on the single rear wheel, just enough to permit a hard stop downhill. I could have put the cg anywhere I wanted. In general, a trike should have a lower cg relative to its width, but a fine study by Paul Van Valkenburg found that they just have a strong tendency to understeer or oversteer at the end with two wheels.
I know of no reputable source that finds dynamic instability in trikes. They have done fine at Bonneville.
