Judging from what Google has been saying to automakers, self-driving cars are still millions of test miles away from actually making it to showrooms, but survey results indicate some American drivers are ready to pay for the technology today. A new survey from J.D. Power and Associates says that 20 percent of vehicle owners tested either "definitely would" or "probably would" spend $3,000 to add fully-autonomous self-driving technology to their next vehicle.

Predictably, there were differences in interest between men and women (25 percent versus 14 percent) and among age groups (37 percent of 18-25ers versus 9 percent of 57-65ers), as well as between premium and non-premium car owners (31 percent versus 18 percent). It looks like drivers were expecting self-driving cars to be cheaper though, since 37 percent of respondents answered favorably before hearing the price.

Call us crazy, but in the US, at the $16.57 median hourly wage being able to get work done during your half-hour commute would be worth about $4,140 a year, which would make an extra $3,000 for autonomous driving a steal.
