I've been trying FSD V11 for about 2 weeks now (in the GTA (Toronto and surrounding areas) in Ontario), and honestly I've had to disable it. It drives better and worse than V10 & Autopilot. I have FSD set to agressive. Here are the problems I've experienced thus far:
1) considerable hesitation with lane changes on the highway, so much so, I've been honked at. FSD sometimes makes multiple attempts to change lanes, but I end up having to take over since it hesitates so long. For example, on a busy highway, when you want to change lanes, it's pretty quick. If you signal and you don't change lanes, you're implying to the other driver that you're letting them pass you first before you change lanes. Since FSD hesitates so long to change lanes after signalling, I've gotten into situations where it has engaged and cancelled the signal multiple times because other drivers think I'm letting them pass. I mean it's a difference betwen 10 seconds and 5 seconds, or something like that, but it's causing a lot of confusion with other drivers.
2) somestimes FSD will not signal when changing lanes into and out of merging lanes (highway or streets)
3) on streets and highways FSD seems to want to go to the end of the merging lane and then change lanes to merge. If it can't merge at the end of the merging lane, it'll keep driving onto the shoulder and try merging. Maybe this is how other places do it, but here (in Ontario), it's illegal to drive on the shoulder, and usually you merge onto the regular lanes at the first opportunity. If there is none, you stop at the end of the merge lane.
4) It's done a bunch of lane changes in an intersection which is illegal in Ontario
5) when turning left, FSD will stear to the right a bit and then left. This confuses other the drivers to the right of me since it looks like I'm attempting to turn right instead of left
6) FSD seems to bias to the other side of the lane away from trucks, sometimes unecessarily. If the lane is straight, that gets a bit uncomfortable since there may be traffic on my other side.... or a wall, which I'd prefer not to get any closer if I don't have to
7) I've blown through a 2 stop signs, obviously illegal
8) Can't seem to cancel lane changes, it says to press the signal button (I have a Model X), but when I do, it either re-enables the signal soon after, or there was a small window of opportunity to cancel a lane change and I missed it.
So there are just the problems I've had, I'm not saying FSD is crap, I know I signed up for early access beta, just pointing out some of the issues I've noticed.
Hopefully someone at Tesla reads these boards, I'm not sure how else to get this info to them. The car does ask you to comment why you disengage FSD, but you can only do that by tugging on the steering wheel. There doesn't seem to be a way to make a note about FSD's performance if it does something that doesn't require tugging the steering wheel (ie. blowing through stop signs, failing to signal lange changes, or signaling for a lane change that isn't necessary or not valid).
I've given it 2 weeks, but I've had to turn FSD off and go back to Autopilot only.
The same route to and from work, around 30 km one way usually requires 3-4 interventions.
