Believe it or not, this happens sometimes, accidentally. Some students with partial vision expressed fear of carrying their canes in public, due to the cane being an unmistakable sign of blindness. One woman's wallet was stolen in a grocery store, by a child. Most visually impaired people are not born blind. Unfortunately, bus services generally operate under limited hours, especially in less-populated areas.
Taxis are too expensive for the blind person on a limited budget.
Services designed to transport the disabled are notoriously inefficient. Some students must leave their homes hours in advance to be sure of arriving on time for classes. Offers of transportation for blind friends, classmates or coworkers most likely would be greatly appreciated. However, the newer cars make little noise and can confuse a blind person. Luckily, the student was not hurt, but he was badly shaken up by the incident.
