I will second the suggestion for a dash camera, they can record audio automatically without need for user intervention.
Another option is to just use a voice assistant, I usually quickly ask my watch to start a voice recording beforehand to ensure there is a record of the interaction.
One thing not mentioned, BTRFS supports transparent compression which hypothetically can increase the longevity of SSD media by reducing the amount of writes to the drive.
I say hypothetically because further information on use case (potential write amplification from CoW) could nullify those gains — but frankly, SSD write longevity has improved so much that it is not a huge issue at this point.
