Personal preferences are always subjective, so each to his/her own as to which features we find useful - or not. Some features just take some getting used to, after a while their attributes might become more apparent. About a year ago a friend of mine told me how Lane Assist on her 2019 BMW saved her life, and possibly others. Returning home late evening after a gruelling 3 day conference interstate, she foolishly (by her own admission) drove home from the airport whilst dog tired. Collected her bag, hit the freeway and then momentarily dozed. Lane Assist vibrated the wheel which stirred her, then did it's thing to keep the car in lane. It gave her a nasty fright and she has vowed to take a cab if seriously fatigued in future, but the fact remains that LA and ACC were there when needed most. Probably goes without saying that she wouldn't be without those features and based on her experience alone, nor would I. Maybe disabling LA and ACC has merit in some driving environments, but the default to ON is no bad thing IMO.
