I make every possible journey by bike, I will occasionally use public transport shudder when, for example, i'm expected to arrive somewhere looking presentable, and the bike isn't a viable option. When I get a car, I will still do the same journeys on my bike as I did before, the car will only be used for recreation (hoons [equivilant of bike meets, enthusiastic car owners get together, talk about their cars and drive for some distance at the quiet hours], track days and tinkering).
So in short, I use my bike for every possible journey, which is the vast, vast majority of them.
