What was introduced in 1980 to reward 'good drivers' regarding license renewal?

The introduction of renewal by mail in 1980 was a significant advancement aimed at rewarding good drivers. This option made it more convenient for individuals with clean driving records to renew their licenses without the need to visit a DMV office in person. Providing a streamlined process, renewal by mail not only reduced waiting times at the DMV but also encouraged safe driving practices by allowing good drivers to enjoy the benefits of their responsible behavior.

In contrast, the other options do not align with the intention of incentivizing good drivers. Renewal through in-person visits typically involves more complexity and time, which does not specifically reward safe driving. Online tests, while convenient, were not implemented at that time and do not directly relate to license renewal rewards. Automatic renewal if no violations occurred does provide a form of incentive but differs from the established mail renewal system introduced in 1980.
