Earlier TACC has not locked to cars which it sees first time when they are at full stop. This has lead to situations as this https://www.youtube.com/watch?v=0X2ftEXG7IE Recently this has maybe changed? At least this is my impression. Today I tested this by activating TACC when I came to my home yard. Only other car was my other car which was parked. I approached it from behind and TACC locked to it. Edit: mods, please ad question mark to title I don't want to cause any accident, if I'm wrong.
