I'm not a professional auto-mechanic but enjoy working on my car and do most of the simple mechanical repairs/maintenance myself. For example replacing the disc brake pads and rotors is fairly simple and requires little investment in tools. However as cars are becoming more computerized, many other things are nearly impossible to work on and requires specialized diagnostics tools and computers to fix, even adjusting some of the headlamps is not as simple. With electric cars there's even less opportunity to work on mechanical stuff.
So my advice would be to think long term, keeping in mind that perhaps in a decade all cars would be electric and most of the auto-mechanic work would be limited to hooking the car up to a computer, reading the display and doing what it tells us to do (e.g. replace computer # 240)
