The high sharp corners are indeed intimidating when Cybertrucks pass near cyclists.
Paradoxically for a vehicle that's surely received oodles of aerodynamic attention, it at least doesn't seem like a design that might push a pedestrian to the side or lift them up onto a hood, but rather knock them forward (and then under the vehicle).
A Cybertruck crossed in front of me at a traffic light this weekend in my first Cybertruck encounter as a cyclist. I was surprised by my lizard-brain's involuntary concern as the hood's corner passed by.
Edit to add: it seems like a wide vehicle, too, which adds to the effect.
