One thing most often missed with bike-curious people, like yourself, miss is that the roads taken by bike are usually not the ones you’d drive.
A car route is often a poor choice when riding a bike. Avoiding fast moving cars means avoiding those dangerous areas. Pedestrians die because they don’t have an alternative (parked across the road, or it’s near home, school, etc).
For example, I’m at a friend’s place and I rode my bike here. The path I take is through slower neighborhoods and dedicated trails. If I drove my car, I’d take a very different route.
My advice is to think of some regular trips you make; work, shopping, or otherwise. Then use Google or Strava or other mapping software to see what their suggested bike routes are. You may be surprised at what’s available. I know I was when I started biking more regularly.
Also there are health benefits. If you’re not exercising every day, then commuting for 5 days by bike absolutely will improve your health. I’ve lost a ton of weight. Take a look at how deadly heart disease is for folks without regular “walking 20 minutes a day” exercise is.
Wow, that’s not great. You have my condolences and I hope you manage to convince your city to put some money into a frontage road or path of some sort. I’ve seen some pretty nice rail trails and the like in very small communities, but they take a lot of work and time.
