3 month-old '23 MYLR with 4,400 miles and probably two-thirds of that on FSDb.
Currently on 2023.20.7 with FSDb 11.3.6.
FSDb does "okay" for me when driving straight ahead - the biggest issue is random, unnecessary lane changes. When it comes to stopping and turning, it is often somewhere between useless, frustrating, embarrassing, and dangerous, so lots of interventions are required.
I get nags every several seconds like everyone else and always satisfy them before the "beep stage".
I'd say I'm more cautious than the average driver with good driving skills.
Yesterday, I got my first strike. I have no idea why, when, or where it occurred - I didn't know about it until the next drive when I got the "telemetry data shows improper use" message.
Part of me is frustrated over this - it's like I'm paying to be falsely accused of a crime, but the other part realizes his insignificant this is.
