9. Emission-free driving
Until your local electric grid is fully powered by renewable energy sources like geothermal, wind, solar, and hydropower, a plug-in electric car isn’t truly emission-free; it still has a carbon footprint (although smaller than gas-powered vehicle's). The good part? Current plug-in cars will only get cleaner as more renewable energy sources go mainstream. So the holy grail of green commuting -- a nearly emission-free drive -- isn’t just a pipe dream.
10. Key-less cars
Biometric devices will recognize your voice, scan your retinas, and ID your fingerprints to allow you to enter and turn on your future car. There are plenty of benefits: you could allow buddies to access your car on demand (and set a speed limiter on them), and the tech could make car-sharing services simpler to use. The only problem: without carrying a keychain, you’re going to have to figure out where to put that fun little plastic soccer ball you got at the Dallas Fort Worth Hudson News that one time.
