The choice to ride with or without a helmet is different for different people. It depends on where you are going, how many other bikers take that route, how fast you will bike, to what extent is it biking in traffic and what just bike trails, and also have you been there before, and do:you think:you should always wear a helmet. One weird factor is that people (car drivers and bike riders) have a certain tolerance to risk, so cars will get closer if you have a helmet on.
I bet that people also drive with a bit more risk tolerance when they are wearing a helmet than otherwise, and of course more likely to get that helmet for a fast, risky, fun ride than a quick trip to the grocery store.
Interestingly, if you are seeking to reduce your personal odds of dying, it is a no brainer to bike. The cardiovascular health benefits outweigh the chance for getting hit by a car.
