Near accident on morning commute

On my ride in today just past Central/Kings on 7th st, I was nearly sideswiped by a truck with the company name 'Service Express'. I don't think there was any space between my head and the mirror of the truck, and as it passed, there wasn't much room there either. I was able to keep my line, blurt out an expletive, but not catch up to the vehicle. I thought about calling the company (there's a local number), but what would I say? I didn't get a license or a truck number, and I couldn't catch up after it passed. I think I need a rear view mirror. What do you like out there - mirror on the glasses or mirror on the bike?
