I no longer try and carry everything I might need. At one time with a bit of mechanical knowledge carrying such an array of tools might have got you out of trouble with a few roadside breakdowns. I've even changed a head gasket in a layby (on a 1931 car)
But now I only have the typical diy emergency breakdown tool kit of a few cheapo quality socket sets, spanners, multi tip bits ,and a few other bibs and bobs. Enough to maybe investigate things, or loosen or tighten something. Plan B is breakdown cover,. Plan C ,if I really know I can fix it myself with the correct part or tool I might buy them local to the breakdown. Never had to so far but its an option.
