No, on what was reported in the news. The train was rolling at well 
above 2x the legal speed limit without any positive trail control 
enabled. That does constitute a serious design error in my book. Design 
includes the enabling or disabling of features that should have been 
available.

See below. I never said it is 100% fail-safe. No system ever is but it 
is much safer versus what we have in the US (or rather, don't have ...)

It normally won't even let a train onto the track in opposite direction 
anywhere close to another. It'll stop it.

To some extent, yes. However, not when witnessed personally. Most people 
cannot forget a gruesome accident scene even if it was decades ago. I 
still remember one from my childhood days, in detail.

My philosophy is that if we can do better in some area then we ought to.
