Last year a transit bus passed me within a foot. I ended up on the grassy shoulder. I was quite shaken by the incident. I wrote to the transit company regarding the incident with all the details. A supervisor got in touch with me for more information and never heard back from him. I still cycle the same route and have been fine since. I would like to think that my writing to them has help. Or it could be just by chance that I have not encounter the same driver.
