People still aren’t ready to accept self-driving cars, according to a new study.

Researchers Brandon Schoettle and Michael Sivak from the University of Michigan Transportation Research Institute recently conducted a study to determine the general public’s opinion on self-driving cars and whether autonomous features are even welcomed by motorists. A total of 505 respondents over the age of 18 completed full surveys with 52.9 percent of respondents being female.

When asked about acceptable levels of vehicle automation, 43.8 percent of respondents said they preferred no self-driving features while 40.6 percent said they’d prefer partially self-driving features. Completely self-driving vehicles were the least preferred, with only 15.6 percent choosing the option. The statistic carried over to how concerned a person would be with riding in a self-driving car, with 35.6 percent of those surveyed saying they’d be very concerned. Only 10.9 percent of the respondents chose not at all concerned.

As for Google’s wish of getting rid of the steering wheel and pedals, it might not sit well with vehicle buyers. Of those surveyed, 96.2 percent said they’d want to have a steering wheel plus gas and brake pedals available even if their vehicles were self-driving.

This is the second year the study has been conducted, and the levels of concern for riding in completely self-driving vehicles stayed relatively consistent. For example, last year’s survey had 35.9 percent of respondents saying they’d be very concerned while this year was 35.6 percent. As for inputting a route or destination, users preferred touchscreens (37.8 percent) over voice commands (36.2 percent) while most respondents (59.4 percent) prefer to be notified of a need to take control of a partially self-driving vehicle with a combination of sound, vibration and visual warnings.
