Timothy Lee:

More Americans say they they’re more worried about the prospect of self-driving cars than excited. They’re afraid that the technology will take jobs away from taxi and truck drivers, and they’re skeptical that the technology will save lives as supporters claim. Overall, just 32 percent believe that self-driving cars will improve the driving experience, compared to 48 percent who don’t think so.
 And for all the hype surrounding ride-hailing services like Uber and Lyft, the vast majority of Americans say they never use them. Most of those who don’t use the services say it’s easier to just drive their own cars.
 The survey also reveals a massive age gap in attitudes about these emerging transportation technologies. Americans over 65 are way less likely to have used ride-hailing services, and they’re particularly skeptical about the potential benefits of self-driving technology.
