I find these a bit annoying, as I think the side effect is that they are basically main beam all the time otherwise, and only dim selectively.

Which is great and all, but means things like they are projecting FRICKIN' LASERS into people's homes (especially when turning) or if you are a pedestrian that it doesn't detect properly (e.g. at some distance down a cluttered urban road etc) you get someone driving at you with really very uncomfortably bright lights shining in your face (I get this a lot when running at night - perhaps the models detect a pedestrian walking but not jogging?).

I am sure it works great in controlled conditions (and I have seen YouTube videos out on the clear open road where it detects oncoming vehicles nicely) but it feels pretty ineffective and anti-social in an urban/suburban environment, at least to me.
