I find I automatically take over instantly when it does something unexpected - maybe I'm lucky but it doesn't cause any adrenaline rush - just mild irritation,
Yes. Highway / freeway driving is pretty good.
In UK apart from motorways ( because traffic flow is uniform in each direction) it is pretty unreliable at the moment. We have so many cases of parked cars right on edge of the highway, and fairly main roads where you regularly have to wait for oncoming traffic to clear before you can proceed.
Also not so encouraging that b-pillar cams are fogged up so often. Assuming they have a role in FSD, it had better be a minor one!
