Bummer about your fall. I hope you don't find and hidden injuries later and that's it just the unpleasant minor issues you've mentioned. It's all well and good to look at getting cars and obstacles out of the bike path. I commend those efforts.

However, the reason for the fall was not the car. The reason for the fall was the driveway lip catching the front wheel. Sorry but I think the best advice here is to remember that cracks, curbs, lips, rr tracks, cobblestones etc can catch a wheel, you always have to look out for them. You said yourself that you've done that maneuver alot. You probably just didn't do it right this time, maybe complacency? FWIW...
