Is it possible to automatic switch of the power of the ignition coil if the ignition is on but I am not driving? Reason is that the ignition coil can be very hot if the breaker contact is in a unfavourable position.

A high-pass rc filter ~50-100Hz in front of T1, would solve your problem. But I don’t know if the car will start then.
Starting an engine is at a low revolution.
Besides, I think a bobine can handle the heat, because in a standard config, with just breakers, the same issue will arise.
Then, your ignition should be very reliable. It should never stop because of such filtering.
You could be better off with a processor circuit, wich could have some intelligance . But again, I don’think it is needed.
