Used my TJA and HBA for the first time today. TJA feels weird. Resting your hand on a constantly moving steering wheel isn't that straightforward. Didn't get chance to see if it would resume from stationary after a period > 3 seconds. The normal ACC definitely doesn't resume after 3 seconds.
The new HBA is amazing even on xenons. It reacts so quickly to dip a single beam while keeping the main beams on. Well I assume it's reacting quickly, hard to tell for sure, but nobody has flashed me yet, and that wasn't the case with the older HBA
