Cars can fail, you have to leave enough room to allow cars behind to stop in time to avoid a (cascade) crash.
- aeternum 4mo agoThis is mostly due to human attention and how the human vision system works.
- jraph 4mo agoThere's also inertia, especially for cars that heavy. You can't go from 140 km/h to 0 instantaneously. (yeah, taking 140 km/h, quite high for a car especially in tunnels like this, but anything slower would be slower than our slow trains and would be quite disappointing)
