I had an accident recently as a cyclist with a vehicle, and I thank my helmet a lot for my lack of injury. The vehicle was a van, and turned right across me going straight (which normally I'd see clearly and avoid, but the way they hesitated implied they'd seen me so I rolled through. Alas.) I'd wager I was going around 20mph/30kph as I hit the side panel. Hips/shoulders first, then I felt my head whiplash into it. Without a helmet, I'd expect at least a mild concussion. With a helmet, I was able to roll away relatively unscathed (minor cuts/bruises) after we exchanged details. Helmets can help at all/many speeds. They're not a perfect solution, but they're great sometimes. Don't discount them so bluntly :)
