Applicable to cyclists too. Take a breather for a minute and let people on and off streetcars safely.
Personally, I like to stop in the middle of the lane to act as a barrier to any cars behind me who are thinking of passing a stopped streetcar.
An astonishing number of drivers simply sail past those open doors. Some, taking the opportunity to get around the streetcar that has been slowing their progress, step on the gas and pass by like stock-car racers.
Cyclists are just as guilty, if not more so. When a streetcar slows as it approaches a stop, many speed up to get by and avoid the effort of coming to a halt and starting up again. Often they don’t make it – and whiz through a crowd of people.
