The auto-dipping is a problem I find as well.
In fact a few years ago, we went out for a walk over Christmas with family and a family member drove us to a nearby Parkland. Coming back in the dark, I noticed that in fact the headlights seemed to dip more often than not after they'd passed another car on the hills/bends on the way back rather than before - suggesting that either the system didn't work or something was faulty in the setup.
It's not just headlights though - I'm always getting incredibly frustrated by those drivers who seem to want to blind the person behind them at traffic lights or in a traffic jam - once you're stationary and the car behind has also stopped, there is absolutely no need to sit with your foot on the brake pedal - please just use the handbrake and let your engine turn off (if it has that functionality) - you're then slightly less polluting both in terms of emissions and light and also not blinding other drivers.
