I wouldn't be surprised or take it personally. If you keep to the right as you approach a place where right turns can be made, you should expect to be right hooked, whether it's a cop, bus driver, taxi driver, or soccer mom.

As you approach any junction where you are going straight, look back over your left shoulder, negotiate/signal as required, and, when it's clear, merge left out into the space that is between the left and right tire tracks used by through vehicular traffic in that lane.
