In a conversation with some folks from the millennial generation, we got to talking about cars and bicycles. I mentioned that I never learned to drive in part because of environmental worry, but also because I was afraid of my own absent mindedness and I didn't want to cause an accident at 60mph.
We discussed how appalling it is that over 30,000 people die each year, in USA, due to car accidents to which they responded. "Let's hear it for the Google self driving car." Thumbs up and high 5ves all around for the Google car. Someone mentioned that the only accident it has been in, so far, was in a parking lot while a driver was over riding the automatic controls. I have hope that in the future, the highway death toll, that we take for granted today, will be much lower.
Hopefully cars of the future will not be the global warming nightmares of today. For instance hydrogen fuel from solar energy.
