There is a study on the practice of lane splitting by motorcyclists:

Result in a nutshell. Lane splitting is safe. The higher the speed differential between the motorcyclist and passenger vehicle, the greater the risk.
LA Times article:

But anecdotal evidence suggests many drivers are uncomfortable with, or irritated by, lane-splitting.
So does research.
More than three-quarters of drivers interviewed for a 2012 study conducted by the California Office for Traffic Safety said they thought lane-splitting was unsafe. Almost half thought it was illegal. Two-thirds said they disapproved, and 7% admitted they had swerved to block a motorcycle trying to lane-split.
IME, that 7% may be grossly low.
I don't know know any rider who lane splits that hasn't had the experience of a passenger vehicle driver either trying to block them, or actually succeeding - a driver will pull halfway into the adjoining lane to block the rider from passing.
It's not just a male ego thing either. I've been on the receiving end of female road rage more than once.
