Global Warming and our Changing World

I was thinking about my car and getting the oil changed. I realized that when Big Oil dies, we'll have to have cars that don't use oil.

Previously I had acknowledged the fact that we're slowly moving towards alternate energy sources like hydrogen and electricity. So no more gas. But I hadn't thought until recently that getting your oil changed will no longer be necessary.

I wonder if future cars will need as much maintenance? Maybe the technology will be such that you just fuel up and go. No oil changes, no checking tire pressure or brake pads. Maybe every step that isn't eliminated will become automated.
