We are getting away from the Tesla truck, thanks in part to me I'll admit.
People make mistakes. As a group, they make the same kind of mistakes over and over. One very human thing to do is make poor decisions about events in the future. A guy named Amos Tversky won a Nobel prize demonstrating this. Or you could just ask anyone who works in Advertising and Marketing.
This is one thing that bothers me about nuclear. "If everyone who runs this nuclear plant makes really good decisions and performs very well for the next 100 years or so..." Well, no. That's not going to happen. Building something (with a very high cost of failure) that requires that much discipline from human beings is not a good idea.
We wouldn't be here if another species didn't cause an environmental disaster a long time ago. I'm talking about those dumb anerobic bacteria that went and polluted their perfectly good methane atmosphere with all of that toxic oxygen. We're a lot smarter than anerobic bacteria. In order to create a sustainable economy and society, whatever comes after us may have to be a lot smarter than we are.
