Relax, Mike. I've spent a total of a year and a half riding around Latin America, and I like topes more now than I did when I began. You don't agree, but this thread is not the exclusive province of those who "confront them day in and day out." And of course I pay for my own bike maintenance: who else is going to do it for me?
For me, they're fun, and often even useful. I've seen all sorts, and some of the worst are in an un-named Indian nation several thousand miles from you (but convenient to my home). The unfortunate truth is that up here I can't use them to pass slower traffic without risking incurring the wrath of the local uniformed law enforcement personnel. That makes Mexican topes far preferable to those closer to home. Count your blessings.
