Here is something I found very interesting on the bus. I mean how is it possible for someone to sit in a seat like this? The passenger may sit on these seats, but it is going to very uncomfortable for sure. The object that supports seats are blocking the space, and there is no space for feet. In addition, the space between seats is limited.
The solution to this design is to find a different object to support these seats such as cylinder object. These cylinder object took less space compared to the objects that support seats in the previous image.
