If you have no bicycle safe routes then sadly you should not be biking. Taking it onto the sidewalk not only endangers you in all the ways described in this thread, it also endangers pedestrians. Someone said they wouldn’t care about getting hit by a car coming out of a driveway, because that’s slower than a car on the street. Fine. But if I step out from my the huge bush my neighbor keeps on the boundary of our driveways, onto the sidewalk, and you crash your bike into me I’m going to feed it to you.
