You’re missing 2 key tools - a tire pressure gauge and jump starter pack.

well your toolkit is overkill and only good for tires lol.

you really should have:

4 hose clamps - large enough to fit a radiator hose but they can also be used to string up a rusted off muffler or crudely hold something together

4 or 10 in one screwdriver

basic slip pliers

needle nose pliers

channel locks

basic 3/8" rachet set metric with some extensions (10mm-18mm)

old flathead for poking and scraping.

set of sae and metric allen keys.

utility knife with extra blades

cig lighter air pump.

jumper cables

leather work gloves

wind up flashlight

at least one black garbage bag

​

the tools all fit in an old metal blowtorch box (maybe 12" wide, 8" deep, 4" tall) and most were sourced from those $1 tool tarps at swap meets or harbor freight

ive had to utilize some of it before or had to help others who were in a pickle in the middle of nowhere. I do maintain my cars and replace stuff before its an issue but sometimes shit happens and its nice to be self sufficient. You run something over that gets wrapped around a driveshaft or caught somewhere under the car youve got pliers where you can cut/pull whatever it is or box knife to slice off whatever you can, ive had those cold asphalt patches get stuck to my tire as i drove over them - nothin like scraping asphalt off a tire and trying to race time before it sets up harder, have had flat tires on wet muddy gravel roads - nice to kneel or lay on a clean dry garbage bag, ive had bolts rattle loose before somehow (maybe forgot to tighten it all the way?) etc.
