Today the official full-year car registration data for 2025 was published.
Looks good. And 2026 will be even better, with the many smaller EVs now hitting the market.
Note: The fleet only increased by 50,000 cars, so the EVs are mainly displacing ICE cars -> BEV fleet is about to pass diesel! 😀

Facts can be easily dismissed. What motivates people to gain insight is recognizing gaps in their understanding and wanting to find out more.

This is the kind of thing that DoorDash shouldn't get to decide. I don't think state laws make sense for this, either. The bike lanes where this will lead to problems are ones that are busy, and that's almost certainly where DoorDash will be more active simply because such places are denser.

Something you don't hear said very often is how a chunk of your water bill is there just to clean up after farmers
When we trawled data on excess nitrate & phosphate pollution (key drivers of algal blooms) we found agriculture was the primary source in rural areas, sewage in urban areas. As Chowns says, to save our rivers, we need to tackle both.

Over time, removing minimum parking mandates results in 2 big changes:
1. People convert excess asphalt into higher and better uses (housing, outdoor dining, etc.).
2. Many people open up their parking to the public, in return for a fee.
