How much dash cam storage do I need for a road trip?

A 256GB card holds roughly 12 hours of 4K footage. For a week-long trip, either use loop recording (auto-overwrites old footage) or bring a laptop to offload each night.

Should passengers use headphones or the car stereo?

Headphones let each person enjoy their own content while the driver focuses. ANC headphones are especially useful for sleeping passengers.
