In my decades of cycling, I've toured, commuted, road raced, ridden off road and done just about anything else one can do on a bike besides BMX or Polo. And, on the roads and trails, I've encountered all manner of obstacles. They include include debris blown or thrown into bike lanes, mounds of snow, motor vehicles parked or idled and animals ranging from a chipmunk (I never would run over anything so cute!) to a pack of macaques and, of course, the random cat, dog or deer.
(I have never had to stop for an elephant, but I did see one from about five meters away on a ride in Cambodia.)
Of all the living beings and inanimate objects that have found their way into my line of riding, I must say that I have never encountered any like this:
Now, tell me: What do you do when a tank is blocking your trading ride? Do you turn around or ride around it? If you choose the latter, do you curse at the driver or remind him/her/them to give you three feet (actually, a meter, since the cyclist is in Kyiv) of space? Does a three-foot/one meter rule exist there? If it does, would a Russian tank operator adhere to it?
