I discovered the walking thing when I was just out of college (and dinosaurs roamed the earth). I had a job for a short time where a relative would drop me off on their way to work and I would catch a trolly, then transfer to an express bus, then 10 blocks of walking to get home (I could avoid the walking if I waited for a "non-express" bus). If I got to the trolly stop early I would just start hiking towards the stop where I would make my transfer. NOT ONCE did the trolly ever catch up to me - and it was a long freaking walk too - about half an hour depending on how I caught the crosswalk signals. I think this is when the light bulb in my head lit up. I had a bike sitting home doing nothing!
