Power delivery concerns for Raspberry Pi in a car

I'm building a custom car head unit based on a raspberry pi 4b. I'm planning to power it from the battery line with a step down converter and controll the power flow via gpio-poweroff device tree overlay. What I'm worried about is rpi freezing, not shutting down and draining the car battery. Is there a real risk of this happening?

AT-ST MOC

After seeing baufman bricks video decided to see if I have the parts to build his at-st. That turned into 2 days of tinkering and ended up in what can be seen in the pics. Obviously inspired by his version. The pictures are rushed coz it started raining :(
