Specifically, 73 percent of those surveyed said they would be too afraid to ride in a fully autonomous vehicle, which is up 10 points over the last survey. Americans also aren't comfortable being a pedestrian around autonomous vehicles either, with 63 percent saying they would feel less safe as a pedestrian or cyclist on the road with self-driving cars.
Another interesting statistic is that while millennials were almost split down the middle in whether they would be too afraid to ride in a fully autonomous car in the first survey, they shifted negatively this time around. Instead of 49 percent being too afraid to ride in a self-driving car, the percentage jumped to 64 percent. In previous studies, younger people surveyed had been more accepting of the technology.
