You did good Grumpy. When you plan for something on a bike like this it happens fast, can't imagine how fast things happen when you don't plan for the bike to do something. If you had hit someone there would have been many more variables to the equation and things could have been a lot worse. I think you did the right thing.
I do have one question, and it's only for educational purposes for myself and other riders who might find themself in a similar situation. What about the kill switch? Did things happen too fast and by the time you got the front end down not have enough time before plowing into someone?
Again, I think you did right by lowsiding. I'd rather hit the ground then get tangled up with other people and their bikes. I'm not saying "you should have done that!". I looped my bike at 50+ years back and totaled it, and everyone said "why didn't you cover rear brake?". my feet were slung from the pegs before I could hit brake.
Glad you're both ok and hope for a speedy recovery.
