  • Abstract:
    This study was designed to: (1) determine any decrement in use of the automatic restraint system, and (2) assess any change in owners' attitudes toward the automatic restraint system over a two year period. The information gathered will assist the NHTSA in trying to predict any potential decrement over time of automatic belt usage if these new systems are introduced into the market place. In an earlier study, designed to ascertain usage of and attitudes toward the automatic system, telephone interviews were conducted with owners of 1978-1979 GM Chevettes and with owners of 1978 VW Rabbits. Both makes of cars when purchased had automatic restraint and starter interlock systems. In the present study, ORC conducted follow-up interviews with 417 Chevette owners and with 441 Rabbit owners from the earlier study who still owned the same cars. Findings indicate that over a period of two years there has been a statistically significant decrease in the percent of owners who report that they use the automatic safety belt. Currently, the usage rate among Chevette owners is 62.8% compared with a rate of 73.9% two years ago. The net decline in usage among Rabbit owners is also statistically significant but more modest dropping from 89.1% in 1979 to 83.0% in 1981. The decrement in usage would probably have been even larger had these cars not incorporated a starter interlock and it was possible to obtain usage data from second owners.
