on EVs as far as I understand the brakes are barely used due to regenerative braking, so they should not be running hot unless the car is being driven very hard.

This is generic knowledge and not necessarily applicable to the Cybertruck however.

Spot on if it has regen braking. I haven’t had to change brake discs/shoes for 5 years.

The system is only so useful and the cybertrucks absolutely have a hydrolic system with rotors and pads:

It's ~~completely disabled~~ "significantly limited" limited when towing.

I never denied the presence of brakes, I just mean for regular driving they are barely used, mostly with hard braking.

I can’t think of anything that might ignite in there, though.

Brakes yo. They get HOT

They will only get hot if they are used and I am implying without hard braking or hard driving they are barely used, so they are unlikely to achieve very high temperatures.

If the vehicle is being driven hard or jerky however that is a different story. Its very heavy and probably heats them up quite a lot when driven hard.

All of this is of course speculation based on what I know about regenerative brakes and regular disc brakes.
