Glad to hear you're okay too. Samething almost happened to me and my wife this summer by a pick-up truck. He was pulling out of a parking lot a restaurant on the left side of the road. We were coming up the road to his right, so were were on the far right lane. I don't remember if he had his turn signal on, but just as we were about to pass him he accelerated out of the parking lot, across the left lane and into ours in an attempt to turn left. I hit our brakes, hit the horn and swerved to the far right side of our lane as my wife and I glared at him. He got the message and slammed on the brakes with an astonished look. Either he clearly didn't see us, or was shocked that we had to audacity to not let him in when we clearly had the right of way.
Since that day I've always covered my horn when I see any kind of vehicle at an intersection, driveway or road set to come into my the lane I'm riding on.
Thanks for sharing and glad to hear you're fine.
