If I leave home at 5:30am, I take Route A. If I leave at 6:30am, I take Route B. If I leave at 7am, I take Route B with a small detour.
If I leave work at 5:00pm, I take Route B with the detour (reversed of course). If I leave at 6:00pm, I take Route B. If I leave anytime after dark, I take Route C to avoid a tricky spot.
I figured it out all by myself over a couple months as I learned the area from the pavement level. Give me a temp, a time, and a place to be in town, and I can tell you the route I will take and what I will be wearing (sweat-free is the usual goal, staying warm is easy).
"Convince me biking is/will/can..." -- my God, for three generations, my forebears were handed a weapon in their teens and pushed out of a boat/helicopter to shoot or get shot. And non-cyclists and first-timers whine about 0.01% likelihoods, millions of vehicle miles, "oh, a driver honked at me today." Get out there and figure it out, or sit on your can. As you wish. Grow a set or just be honest that you can't face your fear. Don't hide behind questionable numbers.
And if you do live in a place with only one route down a maniac-infested speedway, then you have a housing choice to make. I don't need a number to tell me getting passed by 49 18-wheelers at 55mph is a bad idea. Get your house in order, make the move, and enjoy your new digs and your new-found freedom--or not. I make my living with stats, but I don't think 5% of folks use them for anything other than blatant justification for actions taken or excuses for actions not taken.
