There's something you should know about me, if you don't already. Although I've been riding motorcycles for close to 20 years, my riding has probably been about 99% street.
While some might find weaving through the traffic at night on the crowded streets of Bangkok insane, I didn't find it quite as intimidating as I expected. Why? Because I've been riding in congested urban environments for literally my entire riding career.
Sure, Chicago traffic and Bangkok traffic are decidedly not the same, but the sheer number of people out and about in (and on) vehicles, all trying to occupy the same few feet of space at the same time? That's something that's been baked into me from the beginning, since practically as soon as I learned to walk.
