Yeah, I am comfortable riding roads across my whole metro. I wont ride some roads just because the infrastructure isnt ideal for cycling(45mph 2 lane suburban) when a good road is 1 street away, but that isnt because of drivers, its really just because the road itself isnt ideal for bicycle use.
Paved country roads, gravel roads, in town sidestreets, in town main roads...I dont think twice about riding them and drivers seem just fine overall.

I have no more worse experiences with cars when riding a bike than I do when driving a car.
If you look for trouble and insults, you will find trouble and insults. If you are courteous and predictable, others are largely the same.
