The power in your house is significantly less powerful than that in an electric car. There are also clear ways to disconnect the power when working on things in your house, which is not at all as clear in a battery-powered car. They are clearly more dangerous than home electrics. Also, nobody is "disallowing" anything. You can still open up this car. There is just no reason to.
