brakeless
Lacking deceleration means
Brakeless describes something without brakes—a mechanism for slowing or stopping.
The word applies literally to vehicles: a brakeless bicycle careening downhill.
Figuratively, it suggests uncontrolled momentum or recklessness: his brakeless ambition, a brakeless descent into chaos.
