Bike lanes cost money to build, and money to maintain. They may not get worn out by the bicyclists but they still need to have the street sweeper run, the lines painted, signs posted, cracks sealed, etc. Around here the bike lanes are not used nearly as much as the rest of the street, I would say probably the bike lanes cost more per mile used than the rest of the street.
Invented the intermittent windshield wiper. Showed it to the big 3, they said no thanks, but then installed them anyway. Successfully sued Ford, but it took 12 years. Spent the entire amount suing Chrysler who took it all the way to the supreme court. Lawsuits against other manufacturers were dismissed for technicalities (by then he was acting as his own lawyer).
The cycle continues. The things we spent a lifetime learning don't seem valuable to our kids. And that's probably the way it should be. By now computers, like cars, should be a solved problem for most people.
I missed a meeting one time and the team decided to write some standards. I came back and found some great new standards. e.g. Always declare all variables at the top of the method. Every function must have a try catch. All variables are set to nothing at the end of the method. etc. etc.
You can protect yourself easily with antibiotics, so why worry.
Finally, it could make someone else sick, and you'd be in a great position to pick up stuff cheap at the estate sale.
Thing is, this isn't a politician, scientists, or institution saying this, it is the insurance companies. They tend to do a pretty good job of cutting through the BS since their profits are directly connected to actually things right.
On the other hand the insurance companies would benefit if we all went 20 MPH everywhere and never had a major accident. Actually getting to a destination in a reasonable amount of time is of no benefit to them. So maybe they aren't the most objective.
