自転車シェアリングと社会格差:都市生活における自由と平等」の英語長文問題

以下の英文を読み、設問に答えなさい。

The proliferation of bicycle-sharing schemes in urban centers worldwide has been lauded as a sustainable and equitable transportation solution. Advocates highlight their potential to reduce traffic congestion, lower carbon emissions, and offer affordable mobility options, particularly benefiting lower-income individuals who may lack access to private vehicles. However, the reality is often more nuanced. While bicycle sharing can indeed provide increased accessibility, it simultaneously raises critical questions about social equity and freedom. Firstly, the uneven distribution of docking stations often mirrors existing patterns of socioeconomic disparity. Affluent neighborhoods tend to have denser networks of stations, providing residents with convenient and readily available access to bicycles. Conversely, lower-income areas, often characterized by limited infrastructure investment, may have fewer or no stations at all, effectively excluding residents from the benefits of this supposedly inclusive system. This spatial inequality reinforces existing societal divisions and restricts mobility for those already marginalized. Secondly, the financial implications of bicycle-sharing cannot be ignored. While advertised as affordable, regular usage can still impose a considerable financial burden on low-income individuals. The seemingly small charges accumulate, potentially exceeding the cost of other forms of transport for those with limited disposable income. This situation undermines the initial promise of equitable access and further emphasizes the economic inequalities that exist within society. Finally, the very act of participating in bicycle-sharing may be impacted by social factors and freedom of choice. Cultural norms, fear of theft or vandalism, and lack of cycling infrastructure outside of the bicycle-sharing system (such as dedicated cycle lanes) can restrict an individual's ability to fully benefit from the scheme. Such restrictions disproportionately affect those who already face social and economic disadvantages, further limiting their freedom of movement and participation in urban life. Therefore, while bicycle-sharing presents a promising model for sustainable urban mobility, its implementation and impact are inextricably linked to the broader context of social and economic inequality. A truly equitable system requires careful planning, addressing infrastructural disparities, considering affordability for all income levels, and promoting a supportive social environment that ensures freedom of mobility for everyone, regardless of their socioeconomic background.
