That is what I do for a hobby actually, I prefer the non powered sailplanes personally (i.e. bungee launch). I have done fuel planes, and they ARE far superior in power to weight, as well as run time, and sometimes cost, but they are also toys, so spilling nitro in your back seat takes a lot of the fun out of it. And they also don't generally have a payload like real planes do. You are advocating convenience over efficiency here, and the larger scale of a commuter plane means greater losses to avoid something as routine as refuelling a car.
It makes sense for a 10 minute for fun RC flight to carry batteries, but it doesn't make sense if you are serious about efficiency on a larger scale.
