People do not measure the consequences for incurring a penalty of a couple of seconds. The system sometimes does not reward fair play If the affected person ends up losing the car completely, for this purpose they should be given a pit stop after 5 seconds or a penalty lane. This would make people more aware.
Something like the pit assist feature, just auto enabled and unable to disable in the event of penalty to serve.
Although I’m sure most would actually just rage quit.
I see it as feasible, especially if the penalties continue to be polished. In GT7 it works, although I find it unrealistic to make you slow down automatically in the middle of the circuit.
