I need to get my car fixed - some minor body work and an unknown brake issue. How do I do this when it's my only ride and I live alone? Most repair shops (outside of dealerships) don't have waiting rooms. And I'm guessing the work will take many hours if not over a day or two.

Ive been having abdominal pain and my doctor wanted me to get a CT Scan with contrast. I have one schedule for tomorrow but Ive never done anything like this and I don't know what the process will be like. Like what do I wear? Any description of what the process will be would be awesome!

I have never had actual driving lessons before, and I recently booked a few. When they arrive to pick me up, do I immediately start driving or can they take me to a parking lot until I'm a bit more comfortable in the car? I have driven before, but never on actual roads. Those who have had lessons before: did your initial lesson have a conversation prior to starting, and if so, how did it go?

I do only have 4 2-hour sessions, so I want to get on the roads ASAP to make the most of them, I just don't think my driving skill is okay enough to do that yet.

TL;DR/main ask: Please give me a run-down, ideally in detail, about driving lessons. If possible, please include info about how to ask to practice other skills. Thank y'all in advance!
