None of those are in the same “likelihood of death to a person who has common sense” risk category as the high-voltage Mercedes front compartment. See also the various other replies along these lines, such as:

Another way to look at this is, “are there any consumer-serviceable parts within the compartment?” and “are there instantly-fatal wires/terminals within the compartment?”. The pair of answers “no” and “yes” for the Mercedes demand a wholly different approach to risk management and safety design than a gas engine, whose pair of answers are “yes” and “no”.

EV high-voltage are not consumer-serviceable, as a regular consumer cannot be expected to understand high-voltage safety practices. Yes, some consumers know how to service them, but the necessary safety practices that are generally commonly understood for gas engines are not commonly understood for electric engines, and are regulated differently as a result.
