To use your analogy that's buying a 4 seater car and only bothering to check that there are 3 seats in it.
To sharpen the analogy, the system was specified for 193 controllers, was tested for 130, and broke at 153 (unsurprisingly), and then immediately broke again, and then immediately broke again (this is the piece than should be safe guarded against), leading to a complete system collapse, which should absolutely never happen.
