Here's a novel idea: create a ride-tracker in my phone that scores my rides for risk. thought is a derivative of "I keep telling my wife..." (which I never do, of course). if the app tracked me versus known road controls and then gave me positive, constructive feedback, that might be interesting. "BNBB, you can improve your stopping rate at stop signs." "BBNB, you could have a safer commute on these alternate roads with only 3 extra minutes travel time"; "The roads you took last week are 30% high traffic, 20% residential and 50% rural."; "This week you reduced your time on busy roads by 5%"; "Here are the roads near you with the highest number of BMV accidents". "BNBB, you passed thru 17 stop signs on this trip, and you stopped at 3, slowed at 11 and completely blew through 3 of them." Just an idea. If we can't tweak the bad drivers, maybe we can still help cyclists consider different habits.
