Had city bus driver trying to 'squeeze' me off the road on my commute several years ago. Could see him grinning in the bus sideview mirror. Fingers on my bars were less than an inch from the bus, but I was not ready to pile up on the gravel shoulder. Managed to hold my line.
Did get the bus number and called the bus company when I arrived at work. The bus driver's boss claimed he could not know the driver. I gave him time, place and bus number and told him if he did not pursue this I would submit an 'attempted vehicular assault report' to the police. That got his undivided attention.
Called back the next day and checked with bus driver's supervisor and asked what action had been taken, to which he replied the driver had been taken to task and corrective action had been taken.
Checked the bus driver of that bus out on my next few commutes, and sure as heck it was NOT the same driver that had tried to bump me off the road.
Cyclists should be seen and not hurt. We are not invisible, it is just inattention or willfull neglect on driver's part. Appropriate action is a must! Share the road.
