As for btrfs, I think you only get a CoW penalty if there's some other reference to it (e.g. from a snapshot) and CoW is enabled. For things like databases and VM images, you can selectively disable CoW.

In something like a car, you can't afford to just buffer stuff for a while, to reduce the write frequency, because a crash could mean incredibly valuable data pertaining to it never gets written. So, the problem should be solved at a hardware level, by writing to a high-endurance pseudo-SLC buffer. Later, when the car is not in operation, you can migrate that data to a TLC region, or just upload it to the cloud.
