Option D, trips for family and personal errands will increase for both men and women, is the most likely scenario if trends from the last fifteen years of the study continue.
The graph shows a clear upward trend in the number of annual personal trips per person for both men and women between 1990 and 2009. This suggests an increasing preference for personal transportation for errands and leisure activities.
While data beyond 2009 is not available, there's no indication of a reversal in this trend. Societal factors like increasing urbanization, busy lifestyles, and the growing popularity of online shopping are likely to continue driving demand for personal errands and leisure travel.
Therefore, it's reasonable to expect that your car concierge service will see an increase in trips for family and personal errands in the coming years, catering to both men and women.
