    Attitudes toward new technologies often fall along generational lines. That is, generally, younger people tend to outnumber older people in face of a technological shift.

It is not always the case, though. When you look at attitudes toward driverless cars, there doesn't seem to be a clear generational divide. The public overall disagree on whether they'd like to use a driverless car. In a study last year, of all people surveyed, 48 percent said they wanted to ride in one, while 50 percent did not.

The fact that attitudes toward self-driving cars appear to be so steady across generations suggests how transformative the shift to driverless cars could be. Not everyone wants a driverless car now——and no one can get one yet ——but among those who are open to them, every age group is similarly engaged.

When it comes to driverless cars, differences in attitude are obvious based on factors not related to age. College graduates, for example, are particularly interested in driverless cars compared with those who have less education: 59 percent of college graduates said they would like to use a driverless car compared with 38 percent of those with a high-school diploma or less.

Where a person lives matters, too. More people who lived in cities and suburbs said they wanted to try driverless car than those who lived in rural areas.

While there's reason to believe that interest in self-driving cars is going up, a person's age will have little to do with how self-driving cars can become mainstream. Once driverless cars are actually available for sale, the early adopters will be the people who can afford to buy them.
