Unlike most bicycle helmets, typical full-face motorcycle helmets impair your ability to see and hear what is around you. It is actually illegal in some jurisdictions to drive a car while wearing a motorcycle helmet for this reason. Because most motorcycle crashes are the result of the motorcyclist being hit by another vehicle, no helmet means you have a better shot at avoiding an accident.<p>That said, I wouldn&#x27;t go near a motorcycle without a helmet. You&#x27;re going to fuck up and hit your head eventually.
