回复：看楼上 tsc12 的回帖

1. 那些出事的丰田都是offroad 的吗？要玩offroad, 买对了车再说。

Lyedge just proposed one area that "brake override" system may cause problem.

2. Brake override 何时触发，何时解除？

Lyedge just said "Brake ovrride" system may not be as simple as "see brake, then stop fueling engine". I do not know it either. Hope some experts can give more
details.

3. 就算brake switch sensor坏了，纯机械的闸还有seized 的情况，半斤八两（其实，机械部件的工作环境更恶劣）。一辆车抛在路上的可能性多了去了，你要不要一一数来。

Lyedge was just proposing a possible situation at which the "brake override" system might not deliver what driver wants.

If you have pure mechanical brake, most probably you
also have mechanical accelerator. So brake fail, you just release the gas pedal, no acceleration happens.


Just my humble 2 cents. :)
