關於自動煞停誤動作，這有發生過。
但這不能因此否認他的價值。
確實不能因此否認他的價值，但小弟會希望先把已知的各種可能副作用機率告知消費者，讓消費者自行判定機率高不高 (這機率數字或許是客觀的，但判定高不高是很主觀的)，再由消費者自行決定要不要承擔。

畢竟藥品多的是販售上市很長一段時間後，才發現有意料之外的副作用。
也有早就知道的副作用，但藥廠賭它發生機率低，隱瞞甚至銷毀記錄，等事發再說這副作用是意外。
不過至少現今國內各上市藥品的仿單都會詳列各種副作用的發生機率，但車商有公告自動煞停誤動作的發生機率嗎？只要公告就不用吵了，覺得機率低的人花錢享受，覺得機率高的人不花錢安心，各取所需而已。

小弟指的誤判，是車子電腦誤判，不是駕駛誤判。
假使前方無車，只是一個紙片飛過讓電腦誤判，或跟本是電腦自己突然秀逗誤判，車子電腦要啟動煞車，但駕駛確認安全當然是繼續踩著油門，這時正好符合您所列的第二條，車子電腦要煞車，但駕駛繼續踩著油門要加速，不知是否車子會要強制煞車，以測試後方車輛有沒有保持安全距離？
以下引用自Toyota Prius 2016美版(PCS有自動煞停)使用手冊。
P.277
■Limitations of the pre-collision system
●The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
Do not use the pre-collision system instead of normal braking operations
under any circumstances. This system will not prevent collisions or lessen
collision damage or injury in every situation. Do not overly rely on this system.
Failure to do so may lead to an accident, resulting in death or serious
injury.
●Although this system is designed to help avoid a collision or help reduce
the impact of the collision, its effectiveness may change according to various
conditions, therefore the system may not always be able to achieve
the same level of performance.
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
• Conditions under which the system may operate even if there is no possibility
of a collision: →P. 281
• Conditions under which the system may not operate properly: →P. 283
●Do not attempt to test the operation of the pre-collision system yourself, as
the system may not operate properly, possibly leading to an accident.
■Pre-collision braking
●The pre-collision braking function may not operate if certain operations are
performed by the driver. If the accelerator pedal is being depressed
strongly or the steering wheel is being turned, the system may determine
that the driver is taking evasive action and possibly prevent the pre-collision
braking function from operating.
●In some situations, while the pre-collision braking function is operating,
operation of the function may be canceled if the accelerator pedal is
depressed strongly or the steering wheel is turned and the system determines
that the driver is taking evasive action.
●If the brake pedal is being depressed, the system may determine that the
driver is taking evasive action and possibly delay the operation timing of
the pre-collision braking function.
這邊很清楚的解釋了，PCS在油門用力踩下(更正：應該是深踩)，或放開煞車方向盤被轉動的狀況下，會被取消不做動。
這就是您要的防呆，做動強制取消機制來防止誤判了。
P.278，解釋了需要預先關掉PCS功能，避免誤動作導致意外/傷害發生的狀況。
■When to disable the pre-collision system
In the following situations, disable the system, as it may not operate properly,
possibly leading to an accident resulting in death or serious injury:
●When the vehicle is being towed
●When your vehicle is towing another vehicle
●When transporting the vehicle via truck, boat, train or similar means of
transportation
●When the vehicle is raised on a lift with the hybrid system operating and
the tires are allowed to rotate freely
●When inspecting the vehicle using a drum tester such as a chassis dynamometer
or speedometer tester, or when using an on vehicle wheel balancer
●When a strong impact is applied to the front bumper or front grille, due to
an accident or other reasons
●If the vehicle cannot be driven in a stable manner, such as when the vehicle
has been in an accident or is malfunctioning
●When the vehicle is driven in a sporty manner or off-road
●When the tires are not properly inflated
●When the tires are very worn
●When tires of a size other than specified are installed
●When tire chains are installed
●When a compact spare tire or an emergency tire puncture repair kit is used
●If equipment (snow plow, etc.) that may obstruct the radar sensor or camera
sensor is temporarily installed to the vehicle.
不過手冊中也有解釋哪些行駛狀況下(P.281-285)，會導致系統誤判。
(車廠不告訴車主發生機率，反而把什麼時候會發生誤判全寫出來。
情境有缺?這是美國版，消費者一定會告死他集體求償
)比如說路旁都有相當高雜草的道路，爬上坡道頂端、前方有橫跨道路的高架指示牌時，前車是未載貨物的拖板車，前方車輛轉彎入巷時....等等
此時就要靠上面講的防呆機制，由駕駛來取消PCS的做動，或由駕駛自行防止碰撞的發生。
(比如說跟在沒有載貨、急煞的拖板車後方，這就可能反而會讓PCS偵測不到前方車輛因而不動作)
其他廠牌的系統我不清楚，歡迎各位網友提供其他廠牌防撞系統的取消做動方式與條件。
