Focus on expanding the skills you have and improving on what you are good at.
If the car stuff concerns you, print out (and possibly laminate) instructions for basic repairs - with pictures! Keep 'em in a folder or binder next to whatever tools you've got in the car.
Medical stuff...I'd say keep a decent first aid kit around, if that is within your budget. Someone else can always use the tools.
If you are still concerned about first aider skills, brush up on other common adjacent tasks. Off the top of my head, I'll suggest:
- familiarize yourself with the asses the scene [Check-Call-Care] and call-it-in protocols [1 location, 2 help needed, 3 details],
- be the person to go outside and flag down / meet the ambulance,
- be the person who gets the kit / AED,
- learn how to distract distressed or helpy bystanders...
- deal with hazards, or do damage control (keeping people away from ice or downed power lines)
