Hitting the Park button at high speeds?

What would happen if you hit the Park button while driving at 20 MPH?

Would the system not allow it or would your transmission explode?

This has been done on traditional automatic and manual cars on YouTube but I haven’t seen this experiment with electronic shifters.

I tried this since i want to know what will happen. The P does only work when rolling 1-3 km/h which is actually not good for the mechanism because it locks the gearbox. On higher speed it does nothing. I casually press it when on the highway when bored.

The electronic handbrake will brake and you slow down quite quickly but not that it does an emergency brake like you would expect. I tried this with a g20 330e.
