How does a cyclist cause danger to a motorist?

By flying head-first through the window of a car

Presumably this was a side window and it might have been open too?

It was the back window and it wasn't openable (or it was, but it wasn't
closeable!). The cyclist could not remove his head without the assistance of
the driver.
