I have seen the future and it's going to be okay.
Although autonomous cars are what is at the forefront the IECC is more like a think tank for transportation and how it might interface with us - humans.
We toured different labs. One looked like a super clean auto shop, another a super trick fabrication shop, a virtual reality center, etc. It looked like a cool place to work. I mean they've built autonomous race cars! (One, Stanley, was built in conjunction with Stanford University and it won the Grand Challenge, an autonomous race over the Mohave Desert.)
One stop on the tour was with how autonomous vehicles are being designed to aid people with disabilities. Now I don't have a disability (debatable) but I am a baby boomer and we have our own set of problems either now or in the future - At some point we will no longer be able to drive.
I am not entirely sold on autonomous cars but there will be a time in my life when I will be dependent on others to get around. It would be nice to have a car in the driveway that could take me to the store, library, or doctor. Either a car of my own or something like an autonomous Lyft/Uber.
Autonomous transportation may be unstoppable. But I do not see autonomous cars as the savior to all the traffic problems. Simply put unless we somehow get more people out of their individual cars our roads will stay overcrowded. I favor mass transit. So why not autonomous buses? Especially in major metropolitan areas where people have extreme commutes. Trains are nice but the infrastructure isn't really there yet. Buses do not need expensive infrastructure. Just a thought.
