At any rate, the analogy is weak. Testing partners for HIV only makes sense if you're planning to be in a monogamous relationship with them, and ideally should be done 6 months after the start of a monogamous relationship.
You should use a condom with a girl you meet at a bar no matter what. An HIV test doesn't help you at all.
Interestingly when I first got a cycle helmet was the first time I banged my head whilst cycling, though it was a direct factor (didn't account for the helmet when ducking under a tree). Seatbelts apparently cause some to take more risks.
