That route finding info is great. I started (re-started) my commuting a while back but dropped out just because it was so unpleasant. I rode along a high-speed road with a lot of diesel trucks, no bike lane and only a very narrow shoulder area. This road was right next to the freeway so it was noisy and there were so many fumes trapped in an inversion layer I couldn't breathe. So I dropped out.
Then they closed that road and by following the detour on my Vespa I discovered an idillyic, oak-lined paradise of a street. It crosses rushing creeks, has fragrant hedges instead of fumes, seems wider and traffic is lighter and slower at 30-35mph. I restarted the commuting again. If they ever re-open the other route I won't go back.
So yeah, sometimes the route makes all the difference in keeping you on the bike.
