Brain cycles aren’t a limited supply. Besides, you’ll get to feel a nice jolt of serotonin when you remember to sit backwards.

If this crash is anything like the other ones, you might be surprised. Safety complacency tends to cause maintenance failures. Plus the low speed lines are less deadly since the total energy is proportional to velocity squared, and v is low.
In other words, it might be more helpful to look at it as "if they’re run at a higher level of standards, it’s because they have to be".
Statistically you’re probably right, but considering how many brain cycles we waste on non-essentials, it’s just as fun to waste them on this. That way you can start a nerdy conversation with your travel companions, and they can learn to travel without you next time.

You're forgetting about the probability of a crash.
The vast majority of train crashes is due to an impact with a vehicle on a railway crossing.
However, high-speed rail is grade separated, so it doesn't have railway crossings, which means the main cause of crashes is fundamentally impossible.
In other words: Regular rail has a high rate of crashes (with a small number of fatalities each) due to car/truck drivers screwing up. High-speed rail has a low rate of crashes (with a large-ish number of fatalities each) due to catastrophic failure of track & train equipment.

Sure they are.

I can also get that by remembering that I'm conquering a superstition and fitting my behavior closer to real risks.
Zero-risk bias at work. If it’s actually fun for you, don’t let anyone stop you, but I wouldn’t go as far as making it a confident general recommendation.
