THESE days, as we contemplate the future of the automotive industry, we would do well to remember the words of Henry Ford: “Failure is the opportunity to begin again more intelligently.”

For Detroit, there is plenty of failure. But there are also plenty of opportunities to begin again. In fact, there are many new technologies to make cars safer, cheaper, cleaner and more convenient. All these could be adopted by the automobile industry in the near future and without too much trouble.

Here are just four technologies that could be put on the road in the next several years. These technologies — some of which we invest in — are win-wins. They have the potential to improve energy efficiency, cut down on accidents, reduce pollution and make commuting more convenient. They might even help put the American car industry back in the driver’s seat.
