The big difference is that ICE compartments are a known measure, society has been dealing with them for almost a century so the "common sense" on it is well established (we know what mistakes an average stupid person will do and what mistakes an average smart person will do). But Electric is a whole new context, with a completely different set of safety rules, so it will take time to develop a new common sense compatible with those rules, until then there is a very big risk that people may incorrectly apply old safe common sense rules to the new context and get hurt. It boils down to: "I have been [doing something] my entire life and it was always safe, then I got an EV, tried to do the exact same thing and got hurt". From the customer perspective the EV manufacturer turned a safe operation into an unsafe operation, so it is the manufacturer's fault.
