I've had 100K miles on a 'bike & haven't been run over yet. But then, I'm "anally attentive" ... I pretty much assume that other drivers are out to get me.
60K miles on a 'bike is a really long way. You should consider weather as well. It's a lot more noticeable on a 'bike. When the weather's perfect, there's nothing like being on a 'bike. But when it's cold, it's freakin' cold; when it's wet, it's soaking wet; and when it's hot, it's unbearably hot on a 'bike. Some people can deal with it, others are fair weather riders only, and still use a car over 75% of the time. Even though I've had periods where I was pretty hard-core, I needed a car about 25% of the time for carrying larger loads, carrying more people, or simply for comfort reasons.
