Trucks in general are awful for pedestrians and other motorists, but the Cybertruck is made specifically of sharp angles that will rip and tear more than a big flat vertical wall running into you.
While "sharp" edge can certainly break bones, getting hit with a high hood causes people to slam their head into the hood with very little travel time compared to a low hood. Head injuries are far more likely to cause death.
Of course, the risk varies based on height. Sharp edges a couple feet off the ground are far more dangerous to someone only a couple feet tall.
Or consider the licensing requirements (class 2 + an air brake endorsement here in BC), and how difficult it is to buy, and store, a 40' bus, compared to any modern truck.
This is a daft comparison that only serves to muddy the waters, and attempts to excuse excessively large modern trucks
