If bicycle helmets really were effective in such scenarios, then why would motorcyclists and car racers wear such big heavy helmets?
Again, the existance of better helmets doesn't contradict wphamilton's comment at all. If you read what he wrote, you didn't understand it. "High speed" is too vague anyway and with your "
car racer" comment, it seems you are talking about a much higher (and irrelevant) "high speed".
No, it describes why what you said
above is wrong.
I took it as rhetorical since the literal answer is trivial. Race car drivers use heavier helmets because they work better. Cyclists do not, because they are an impediment to the physical activity.
Neither of those answers relate to the question of whether a bicycle helmet is effective at all in a bicycle crash involving a car.
