A scooter is a great middle-of-the-road option. Cheap to buy, economical to use, and easy to drive and maintain. A bicycle is a lot cheaper, and indeed I use mine every day, but for short commutes and to run errands in the neighbourhood. If I lived year-round in a warm weather area, I would probably get myself a little Vespa.
As for a motorcycle, I love them. I had many bikes, and still own one, a quasi-mint 1971 Triumph Tiger which is the last bike I will have, and also coincidentally the first one I bought, back in the days. I no longer ride it and it has been sitting in the parkade for the past few years, and a couple of times a year, I put my leather jacket on and ride it around the parkade for thirty minutes, pretending I am Marlon Brando. This is the only material thing I am attached too, but I am getting closer to getting rid of it. I don't ride mainly because I don't trust other drivers on the road, and I don't trust myself, even if I am a very level-headed driver and by all standards, one that always drives defensively, and always below the speed limit and practicing hypermiling. But riding a motorcycle, very much like a powerful sports car, is fun. We hear that comment every time: the fun factor. Unfortunately, fun and driving should not go together in my opinion. Fun makes us take risks that we would never take if we were driving a Skoda or a moped, even those of us who are otherwise disciplined and careful drivers.
