Why not? This is a useful behavior that is currently emulated by forwarding calls to laptops and tablets with the same account when the devices are on the same Wi-Fi. You could get rid of the Wi-Fi requirement if those devices all simply had an eSIM with the same number.
Hydrogen will not be a threat to any electric personal vehicle simply because it’s 3x less efficient (electrolyze water to split it) and thus 3x more expensive to run.
