I tend to err on the side of caution when it comes to roads and my life, in so far as I'll always take so much more care if I don't have a huge metal box around me. I always check both sides of the road at least four times when crossing on foot for example, although that might be an OCD thing too. You wouldn't just cross a road without looking, so why on earth some cyclists ride like they do and then complain when a car comes a smidgen too close is beyond me.
