Well if your friend is the one responsible from the accident, then yes, he should be paying the car damages.

Sometimes it is pedestrian fault. I was nearly run over by a truck crossing the street trying not to miss a bus that took so long waiting.

It was entirely my fault had he killed me. Luckily I had good reflexes and jumped away, the truck hit my leg at over 100kms/hour while in the air and only made me a small bruise as it rotated in the air with little resistance.

In Germany it is generally the other way round, especially when children are involved. The driver of a car has to take care of pedestrians and cyclists. Even if a driver follows the rules perfectly fine, § 1.1 of the law (you have to take care of others) always beats the rest.

Interestingly, Germany is also the most wonderful place I know for a drive. They're well-trained, considerate, and skilled.

You get what you (let people) pay for. A drivers license costs ~1500€ here.
