Public transportation in Cairo is interesting , there are different level of buses. The most affordable bus is quite crowded but this is not the main concern. The risk is that the bus riders can jump off the bus not waiting for bus stops. This is risk of falling and quite an injury although they know that they have to jump and run in the direction of bus not the opposite -law of motion- but the risk doesn’t really equate waiting for the bus stop. Beside jumping off a moving bus, there is also tendency to cling off the bus door as it moves with door opened. Any obstacle in the street or if the bus driver brakes suddenly, those clinging passengers to the door will have a dramatic fall on their heads.
