(Beaverton, OR)  --  Police say three people were injured as a result of a crash only inches away from a busy restaurant in Beaverton.  Authorities say it's possible the driver suffered some sort of medical emergency, drove erratically for about two blocks, hit a bicyclist, and struck a tree, which caused the car to overturn.  Police say the car also hit a woman sitting outside the McMenamins restaurant in the area of Southwest Murray Boulevard and Allen Boulevard before coming to rest outside the building.  The driver was airlifted to a hospital, and there's no word yet on her condition.
