Self drive? You're having a laugh. I wouldn't trust it to drive to the end of the road, let alone any further. The sign recognition is great, until it picks up signs from slips roads, roads running parallel, at junctions (on the roads you're not going down)... and with that feeding into the predictive AAC (which is the main difference), it can get pretty random as to what speed you're going to end up doing. The bend/roundabout/junction bit of the pACC isn't too bad - it works from the map data so is a bit more reliable - but it's only really usable with ACC set to sport. In eco/normal, it slows down too much and too early (but with the ACC set to sport, there are other behaviours that I really don't enjoy like getting very close to the car in front before even thinking about slowing down, then hitting the brakes - instead of easing off the gas early and only applying a bit of braking if necessary when coming up behind someone). And the lane keeping doesn't seem to be anywhere near as good as it was in my old bear for some reason... and even with your hands on the wheel, if you're going along a straight bit of road it will moan that you need to take over the steering, even though no steering needs to be done!
Fortunately, you can turn the p bit of the pACC off... but then why pay for the travel assist over just ACC? In my case, it's because it was the only way to get lane assist + ACC, you couldn't order the two options together so had to take the travel assist pack. Don't know if that's still the same or if one or the other isn't even available now...
