You are fortunate . . . why traffic is more dangerous than the open road.
I dodged that bullet several years ago: had turned my head to change lanes, and when I looked forward, the line of cars was stopped in the left lane. The next lane happened to have an open spot into which I moved. My wife was on back, and so that was a double bullet missed.
Funny (well, not really, but with life being as short as it is, better to laugh than to cry), I took my wife out on the Rocket for the first time this evening, to go out to dinner with friends. All was fine, and back home, pulling into the garage, I dropped the bike (my wife had already gotten off, and in her "helpful" wife way, was yelling at me, "The bike is not straight, the bike is not straight!" I pulled in anyway, and the rear wheel hit the high edge of the dolly, and I couldn't control it, and over it went. Happily, unlike the sickening "crunch, thud, scrape" of the ST1300, this just went over, and not far, with almost a sigh. Similarly, it was not so difficult to get back up, and by this time my daughter had come out into the garage to see what was all the commotion, and my wife is saying, "See there, you should listen to me.", and my daughter is saying, "Well, I can see both sides."
Glad you're o.k., and as we say in the military when someone returns from a harrowing mission, "That you're alive to tell us about it."
