I can't imagine trying to inflate a car tire with a hand pump! As the article said, that sounds like a lot of effort to expend to just fill a tire with air. I think an automatic tire pressure inflator sounds like a much better idea.
Although, the average person probably doesn't need to invest in either thing. I don't work on my car, so if I need to put some air in my tires, I just go to the nearest gas station.
