You work on an EV like any other vehicle. The short answer to your 2nd question is you learn how and why cars break and people crash into stuff. I have a lot of experience with that. I've been driving for 47 years and I've never crashed a car, or crashed into one, or had one crash into me, and I've never gotten a ticket. That's not all luck. It's "defensive driving". To sum in up you have to drive like everyone else is trying to crash into you and the roads are always slippery, and nowadays like your autopilot sucks.
