Too often, older Americans must choose between their safety and their mobility-between continuing to drive as their abilities decline or remaining homebound and dependent on others after giving up their cars. Seniors, as a result, have the highest fatal crash rate of any driving population in the United States. Prior attempts to address this problem have failed to fully meet the needs of their target senior consumers. Senior transportation programs, often government funded, have typically relied on attempts to convince older people to ride buses or subways; on organizing volunteers to pick up vanloads of seniors for group trips; or offering rides to a handful of specific destinations, such as medical appointments. Finding these options insufficient, many seniors continue to drive when they are no longer fit to operate a vehicle, or become increasingly housebound as they restrict their own driving and become dependent on favors from family and friends.
