In a letter to the sponsors of a California bill, AB 984, the Consumer Federation of America and other groups reiterated their opposition to making digital license plate and registration programs permanent unless clear limits are placed on the ability of the vendors involved in the programs to collect and use the sensitive information, such as location data. The groups also expressed concern about sharing the data with law enforcement agencies without warrants, data security, and the potential for malfunctions to result in individuals’ being wrongly ticketed.
