I looks like there was fire, but it doesn’t look like it came from where the battery is. The battery runs from front to back on the bottom of the vehicle. This looks like the fire was only at the front. So perhaps whatever was impacted caught on fire but the battery never ignited perhaps?
It’s impossible to tell from a single photo, but it looks like the fire was possibly localized to the wheel-well. I can’t think of anything that might ignite in there, though.
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.
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.

Brakes yo. They get HOT

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.

the battery can provide the energy to start a fire somewhere else in the vehicle via short circuit connection
Tesla’s have a pyrofuse that blows on impact detection which disconnects the battery:
