Similar to a Plane Crash, a Car Accident can occur. You can find the location of the car accident on your map and head there by running or walking. Instead of destroyed plane parts, you may see wrecked cars here as well as fallen bridges.

The place may be surrounded with enemies as well, so make sure to head there if you're only prepared. Crates will be scattered throughout containing Materials for crafting. Their time is also limited, so make sure that you have enough Inventory space, as well as time and Energy when you go to that location.
