It's about 50/50 for me, too. I love riding my bike. When I drive, I always feel like such a drone- stuck at the light, fiddling with my phone, the radio, or sipping my coffee. Just like the people in the 5 cars in front of me, and the 5 behind. I feel more like myself when I ride my bike.
My favorite part of my commute is going down my hill. Almost no traffic and some decently bright headlights = flying!
