Rush hour traffic in Utrecht.
Sound on 🔊 if you want to experience that rush hour IS possible without the constant, deafening noise of cars overpowering people talking.

The entrance to the 3-storey bike parking garage at Utrecht Central holding 12,500 bicycles. It’s free for the first 24 hours, linked to the station, and used by tens of thousands every day. This is what happens when a country treats bikes as real transport infrastructure, not an afterthought.

Riding a bicycle is pretty great any time. Catching an early train back Toronto to ride and meet up with buddies at the weekly coffee spot on the North shore of Lake Ontario is even more great.

Properly designed bike infrastructure doubles as an emergency access lane, allowing first responders to bypass gridlocked car traffic.
This completely nullifies the argument that bike lanes are a safety risk for response times. But it only works if you build them wide enough to be functional.

“One mile on a bike is a $.42 economic gain to society, one mile driving is a $.20 loss.”
“Which means that Copenhagen, a city of 1.2 million people, saves $357 million a year on health costs because something like 80% of its population commutes by bike.” #CityMakingMath
Some costs aren’t costs.

Copenhagen, the bicycle-friendliest place on the planet, publishes a biannual Bicycle Account, and buried in its pages is a rather astonishing fact.

Just a reminder, the first 5-7 minutes of any winter bike trip will always have you rethinking your choices, but after your body acclimates, you'll begin to reap the rewards of the joy that is winter riding.

We absolutely should. I talked about this at the Illinois Bicycle Summit a few years ago. This would make a real difference and would likely enlist the insurance industry in making drivers safer to protect their bottom line.
We should copy the Dutch law that always makes car drivers responsible when they hit a cyclist. Not only would it reduce the number of accidents, it would speed up court cases.

So many days in January and February where we drag our batteries inside for the night and put them on a charger.
Cars might work fine in California or Florida, but they’re not practical here in Canada. We have winter.
