It's the bike I feel safest going fast on. The Red Baron reaches high speeds with a lot less effort, but there's little margin for error. The trike has high margin for error, but more wheels to think about and I don't get enough practice riding it fast to have much confidence with corners. Upwrongs all feel like you're going to land on your face as soon as anything goes wrong, unless it's a Brompton, in which case the brakes being merely a polite suggestion is almost but not quite entirely cancelled out by the low terminal velocity, and your main risk is splatting into a horizontal surface like Wile E. Coyote.
