San Antonio seems to be better than the other big cities, but I never pass through enough to swear to it. Fort Worth used to be okay, but that was decades ago. Houston is not too bad if you can get used to having someone tailgating you at 70. I was staying just north of the Loop in Chicago a couple of months ago and saw three guys on naked bikes weaving through 3 mph traffic. If I lived in Chicago, I'd have a Vespa for errands.
