flares – check
spare tire – check
blankets and bit of emergency water/food – check Fire extinguisher, possibly a spare $3 battery socket wrench sold at any parts store? – naaaaaaaaaah! When would I ever use that on something with exposed wiring that contacts and wiring corrode on and runs of cable with no fusing from the starter and fuse panels…
Costs like $40 for this insurance(while in the vehicle) from going full on Chernobyl.
