People do that. Sometimes, at least. I have a high quality (high volume) bike pump at home, and occasionally I use it to check the pressure on the car, or to top off if it's obviously missing something. I find it 100% hassle free and not in the least problematic. But then I have a really good volume on that pump; also I can use my whole body to pump (the type where you stand on the "foot" of the pump and can pull/push the handle by using your full upper body weight/strength). I would probably hate it if I only had my secondary "trail" pump, which rests in my bike backpack all the time. First of all, I probably could not even fit it to the car tire, as it has no separate tube, and secondly it would really be a huge amount of work to get all that volume in. Besides, the not so technically inclined person might not even be aware that it is technically possible to do so (not every pump fits the car valves), and people may not be aware that bikes have higher pressure than cars anyways (well
