In the USA I would commute to work, 11 miles each way, on regular roadways, a few times a week during summer I am older now, and I would never consider biking in Bs. As. The vehicle drivers are too negligent in Bs. As. The traffic signals are ineffective, nonexistent, or ignored. I have seen so many motos down in the middle of an intersection. You can have a thousand bike rides that bring health benefits and effective transportation, but it only takes one incident to cause permanent injury. I would much rather identify as a very timid, scared, less than a man individual, than have screws or pins in my bones, fewer teeth, and even more mental challenges than I experience at present. If you bike, wear a helmet, it could save your life, to which I can personally attest.
