As someone who often commutes by bike, I welcome this development. But it still won't overcome the following major hurdles to widespread bike commuting.
1) Hills. People just don't like them. Biking up them is hard work.
2) Sweat. Most commuters don't want to arrive at work sweaty, don't have a place to shower or even change into dry clothes. This is especially true for women.
3) Flats. A bike gets a flat tire far more often than a car breaks down. Few people want to change a tire on their way to work.
4) Rain. Riding a bike in the rain is not only unpleasant, but also dangerous. Bicycles may be an occasional commuting method for some, but it can never be somebody's sole option because it doesn't account for what to do on rainy days.
