What?

A vehicle (presumably a car, since bikes are vehicles too) gets you and your stuff from point A to point B. Bikes do that too, though at a smaller scale.

If your commute or your errands aren't excessively long or require the use of a controlled-access highway, a bike's a perfectly fine alternative. The limiting factors are seasonal road or bike path maintenance and the discipline of other road users.
