Good grief ...

So, there are a little more than 3.3x as many people today, than there were 100 yrs ago. Also the population has shifted from being primarily agricultural to being urban. Also, the traffic congestion on most roads in the 1900's were not only significantly slower, but far less dense. And does this surprise you?
Perhaps there's a point in there somewhere about why bikes don't belong on the road, or maybe something about how roads in 1910 were designed with bikes in mind, but aren't today. Perhaps some statistic about accident or fatality rates then and now. Damned if I can find it. All I can see is some total non sequitur about how more people should mean more useless laws and regulations. Makes me think I should go find some conservative site to post on.
