The plan for next time (this Thursday) is to intentionally go onto more trafficked streets -- practicing turning onto a street and staying in my own lane the whole time. Today I was mostly chill about going onto ~major streets, but multiple times turning onto streets (low-traffic ones) the car felt really unwieldy to me, so I am v. dubious about this exercise. Obviously this is a skill that people master, but yeah.
In general I think I am getting more comfortable, though. And I mostly displayed good judgement driving today -- and was marginally better at actually paying attention to behind me. I did edge close to the right a few times -- and there were various other times when FCS-Ian would point out/remind me of things (there is a lot to keep track of while driving!).
Parking the car at the end, I was like a foot and a half away from the curb. When I parked I felt like I was too far away, but since last time I'd crunched up onto the curb I didn't want to trust my judgement.
