Inspired: Speed *dips*, because modern clearance and suspension makes taking speed bumps at speed no big deal, but dips still make drivers worry they'll damage their car, and that has the highest level of encouraging compliance

Think much of the over-parenting we despise stems from the early on fear of the driver.
If parents weren't terrified of our streets kids would have so much more freedom and independence which might get them comfortable with their children's ability to navigate the world without them.

The USPS posting a NINE BILLION DOLLAR LOSS!!! sounds terrible. Certainly worse than if you said "USPS costs thirty dollars per person per year" even though that means the same thing and more accurately describes a government service

It’s very odd that we entrust the clearing of public sidewalks (which are part of our transportation network) to private property owners & businesses.
We get results like this business that cleared only their walkways & left the rest of the sidewalk covered in snow.

Trains really are the highpoint of human development. There is no more elegant, relaxing way to cross large distances than in a train. The ability to look out the big windows, read a book, have meal or a drink, walk around and converse with fellow passengers is something magical.
A book and a train is a hell of a combination.
