About 3 years ago I got a job working at a restaurant literally up the street from my house. Except for Winter it didnt make much sense to even start my car so I went out and bought a plain jane cruiser single speed (huffy) just for the fun of riding to work. But as time went on i would also ride the bike to see my family a couple of miles away and other places that would involve roads, intersections, traffic, malls etc. We do have very nice sidewalks to ride on along the way too. I even bought lights and mirror so I can ride at night because sometimes I get out late.

I find that it basically takes me to go see my family (2.2miles) about 10-15 minutes which involves moderate traffic patterns. If I ride to the mall thats about 5 minutes down a busy road with a nice sidewalk/bike route. Obviously a single speed has its limitations going up hill but thats the fun of a cruiser...find your way around those uphills lol...
And theres no shame in walking up a very steep hill lol...its all in the presentation I guess lol.

But yea, commute away with your bike. I am very confident that if you begin your destination, then you will reach your destination no problem lol.
