The former graph illustrates the proportion of ownership of three distinct types of vehicles, namely cars, motorbikes and trucks; whereas the latter chart demonstrates the average amount of time spent utilizing them on the road over a sixty-year timespan from 1960 to 2020.
Overall, it is evident that all the given types of vehicles witnessed upward trends and the percentage of truck owners remained the lowest during the examined period. Additionally, the second chart reveals that most categories exhibit downward patterns, except for cars, where the average time spent driving them weekly slightly increased.
Examining the initial chart, the percentages of car, motorcycle and truck ownership were relatively low in 1960, at less than a quarter. However, these three categories similarly rose rapidly in 1980, particularly 75% for motorcycles, 25% for cars and nearly a tenth for trucks. Moreover, in the next 20 years, the figure for motorbikes peaked at approximately 90%, while the other two figures consistently rose to 25% for trucks and roughly 40% for cars. Ultimately, the percentage of car owners saw a sharp rise, making it the most significant figure among the categories. By contrast, the figures for truck and motorcycle ownership dropped slightly to less than 25% and over 60%, respectively.
Regarding the latter illustration, the average amount of time spent on trucks during 1960 was relatively high at 12 hours per week. Furthermore, this figure continually increased to 14 hours per week before it dropped dramatically to 9 hours per week in 2020. Moreover, the number of hours spent on motorcycles remained the lowest at around 5 hours per week despite a rise to approximately 8 hours in 2000. Finally, the average weekly hours spent driving cars fluctuated between 6 and 7 hours during the timespan.
