The drunk driver put them in that situation but the Cybertruck designers trapped them there.
Compare it to a fire in a building. Yes, the person who caused the building fire is at fault but you would have been alive if not for a fire exit door that doesn't have the standard push latch because the designers wanted to hide a release behind a panel somewhere and you, a building occupant and not the owner with the manual, can't figure it out before perishing in the blaze. (Along similar lines, in a building fire, locked doors are automatically unlocked once the alarms are triggered. That is not the case in the design of the Cybertruck).
There's no mechanical or structural justification to omit a manual door release in the design of the Cybertruck. It was for aesthetics only and as shown, deadly.
The crash is on the driver. The deaths are on the designers and engineers at Tesla.
All cars with electric door latches, including Cybertrucks have manual door releases.
