Ideally, it would be great if OEM's installed a metal tube at the bottom of the oil pan which led up to the front just under the hood. Then you could attach a pump to suck the oil out. Some cars have their filters on top as well, so you would never have to jack up the car, and you could change your oil in the parking lot during your lunch break.

Just attach pump, suck out oil, install new filter, then put in new oil. Would take all but 10 minutes.
