Here where I live, Vancouver, all sidewalks have ramps to allow people who use mobility devices to move around the city.
Also, all curbs have the same height. On the contrary, in Brazil curbs can de very low or extremely high, making it difficult for vision impaired individuals and senior citizens.
The lack of ramps on most of the cities in Brazil make it impossible for someone driving a wheelchair to move alone in the city, as it is necessary someone to help with the many obstacles found along the way.
Sidewalks in Vancouver are well constructed, with a regular surface, making it easy for people with disabilities.
On the other hand, sidewalks in Brazil, when present, are usually in terrible condition.
The mobile carts, common between elder folks here in Vancouver, are nonexistent in Brazil, as there is no infrastructure like ramps in all buildings and sidewalks.
