Left standing at bus stop

I have just been left at bus top J 1-6. The driver had closed his doors and I was running up to the bus. The other passengers were even signaling to him to open the door. It's not like it was in peak hour traffic and that the bus was running late. I feel that this is racially motivated. I use this bus route everyday and I have seen drivers open the door for whites and coloureds after the door has already closed or when the driver has driven past the bus stop.
