Aviation by an order of magnitude. Batteries are nowhere near the energy density of kerosene, so there’s a lot more weight, that doesn’t diminish during flight. Charging in tight turnaround times.
Pure safety - if a plane needs to make an emergency landing it can purge the fuel tanks. It can’t drop a massive solid battery. Fuel fires in flight can be killed off by stopping kerosene flow to the engine. It would be the fuel source itself which is on fire with a battery, and again no way to get that away from the cabin. Developing a fully fire-resistant battery would be essential.
Psychological factors - a roaring engine feels safer. A whisper quiet plane will be very disconcerting for most passengers initially.

Are you kidding? Quieter transport sounds like a blissful improvement to me.
EVs have a greater rate of motion sickness reports than ICE cars, now add another couple of axes of motion.
