In one future world, we will live in the less expensive suburbs or rural areas, and come into the city for work in our driverless vehicles. To avoid expensive parking fees, we’ll send our vehicles out to roam around, hang out at the mall and grocery store and come pick us up when work is over. The possibility of hoards of driverless and riderless vehicles on the streets and in parking lots, hovering, just waiting for instructions, seems like the opening scene of a movie where you know things are about to go terribly wrong.
This scene of the zombie vehicles taking over the parking lots and streets of urban centers is quite possible. But a University of California professor is working to save us all.
A professor at the Institute of Transportation Studies at the University of California, Davis, Fulton has been publishing work on a mobility program for the future world. He says, and back up his claims with science, that three things have to change simultaneously for the future of transportation and climate change to work: electric vehicles, autonomous vehicles, and ride-sharing. The Paris Agreement in 2015 hopes to keep global warming at 1.5 degrees. Some estimate this means 100 million new electrical vehicles on the road by 2030.
The snake in the woodpile is the lithium-ion battery, and the extensive mining for raw materials that is needed to supply the battery power for electric vehicles. There is concern that the current levels of energy use to produce these batteries means they will have a higher carbon footprint for much of their life, compared to current petroleum-based internal combustion engine vehicles. We can hope that the scientists who are working on this technology can continue to improve methods and materials used in manufacture, and lower the carbon footprint of these batteries.
