A story in The Columbus Dispatch and other news media report that American Honda Motor Co.  has told some 2.2 million of its Honda and 2.7 million of its Acura owners that their email addresses have been potentially compromised because of a security breach at a Honda vendor. In addition, the login names, e-mail addresses and vehicle-identification numbers of the Honda owners were also likely compromised.

Honda is suggesting that those affected change the passwords to their accounts, and to watch out for phishing attacks:

"Be cautious of unsolicited emails requesting personal information. Often, these communications can look official. American Honda Motor Co., Inc. will not send emails requesting social security or credit card numbers or other personal information."

There is speculation that the breach is related to the Silverpop breach that was disclosed a few weeks ago and affected McDonald's, among others.

If it is, the question is why has it taken Honda so long to disclose the breach?

China has more EVs than any other country—but it also gets most of its electricity from coal.

EVs have finally come of age. The total cost of purchasing and driving one—the cost of ownership—has fallen nearly to parity with a typical gasoline-fueled car. Scientists and engineers have extended the range of EVs by cramming ever more energy into their batteries, and vehicle-charging networks have expanded in many countries. In the United States, for example, there are more than 49,000 public charging stations, and it is now possible to drive an EV from New York to California using public charging networks.

With all this, consumers and policymakers alike are hopeful that society will soon greatly reduce its carbon emissions by replacing today’s cars with electric vehicles. Indeed, adopting electric vehicles will go a long way in helping to improve environmental outcomes. But EVs come with important weaknesses, and so people shouldn’t count on them alone to do the job, even for the transportation sector.
