What are practical examples of a serious danger?
A danger is serious, for example, when a properly maintained vehicle can no longer be steered. The complete failure of the steering system during driving without advance notice resulting from the breaking of a steering spindle, steering link or a wheel is an example of a serious danger. There is no serious danger, however, when the power assisted steering fails, as the vehicle can still be steered within legal limits.
Cases can mostly not be generalized. Individual cases are often observed.
