Wow, I'm glad that you came out of that okay. Those situations suck and there's usually not much you can do when faced with a crazy, unpredictable driver.
I had a similar thing happen to me when I lived in Tempe, AZ back in 1998. I had just pulled out of my apartment complex and was headed down a six lane road (three lanes both directions and a center turning lane) on my Katana 750. I was also 29. Hmmmm.
Check the streetview:
3394 S McClintock Dr, Tempe, Maricopa, Arizona 85283, United States - Google Maps
I saw a car on the left side of the road leaving a business. It was an older lady driving and she started straight across the other lanes. I started slowing down, but figured that I didn't have much to worry about, since there was a center turning lane and three lanes in my direction too. Long story short, she decided to go straight across the entire road to a business on my side and never saw me.... I was
almost stopped when we made contact, and my can-o-tuna just glanced off of the side of her car. Somehow, I was off of the bike and I still don't know how that happened. I had no injuries and the kat just had busted up mirrors and some cracked plastic.
Slowing down does seem to minimize the damage potential and I got lucky in my case. I could have just as easily accelerated again like you did.
Now that I have children, I think about the consequences of riding more, but I can't give it up as it's such a part of me.
