You guys/gals are hilarious !
Most of the time it's obviously not needed. But several times in the past couple years we've had some slow leakers on our cars. Pump them back to normal in a minute or two and off to Les Schwab for a flat repair; mostly small nails and other road hazards. First time I used a bicycle pump was just such an emergency; I myself was surprised it worked. Much more convenient than exchanging the tire with the spare in the trunk (so long as it is really only a slow leaker).
