This video show me doing a left merge from BL into adjacent vehicular lane at night with lots of hand signalling and looking back and minimal response.
This is a different place than I was refering to, but I post it to give a sense of traffic volume and speed as this is typical during my commute.
I just uploaded it to YouTube today, but it is from Jan 5th, 2006 before I got an HID headlight (I had a much dimmer 10W/6W dual Halogen at the time)
