@jwildeboer Tesla (admittedly an American company) seems to diagree and think that a waiver signed by by the user, but required for the use, is a complete get out if its 'autopilot' or defective by design door handles kill or injure you.

Pharmaceutical manufacturers are also not responsible if a user misuses their product, eg to poison or overdose someone. They are clearly responsible if the product doesn't perform as promised or they didn't do due enough due diligence as to possible side effects before they released it and someone who uses it for its declared purposes is injured by it.
