A peaceful and relaxing video.
Especially nice to see drivers yielding when required as well as traffic signals that sense the presence of vehicles rather than arbitrarily timed signals that always seem to keep people waiting.
It is all so … intelligent and civilized.

A rare week of snow in the Netherlands! ❄️ I took a 19 km ride through ’s-Hertogenbosch while the city was covered in white. Slow, real-time, and surprisingly safe — despite what some online comments suggest! 🚲 (Includes a Short as well)
Ride in the Snow (’s-Hertogenbosch, Netherlands)
Last week was exceptional and this called for an extra post! The Netherlands had not seen this much snow in about five years. The video I recorded and published last week was filmed in Utrecht on Monday morning, when many people were heading to work for the first time in 2026. At that moment, we had no idea what was still to come.

The reason I go on about self-driving cars is that it's like watching somebody spend 20 minutes using a thimble to fill a kettle and them saying "I can't wait for the glorious day when I'll have a robot to carry this thimble for me"

Beginning to think that the only way to get local DOTs to stop installing these useless plastic bollards is to pass a state bill forbidding their use.

NEW STUDY: Induced demand means adding highway lanes only increases automobile traffic and urban congestion.
Same works for bicycle infrastructure + train tracks—build it, and they will ride.

When talking about climate, I’m now starting with:
“Everyone makes their own decisions about climate action, but I'm walking, cycling, taking the bus/train/metro, avoiding unnecessary air travel, & not overeating or wasting food."
I follow up with:
“What are your choices for reducing CO2 output?"

Yeah, 1.5C is basically here. We'll just have to live with the consequences of 1.5, 1.6, 1.7 etc until we can't adapt any more.

While sitting on a long hold with my health care provider, I came to the conclusion that nothing says “Your call is important to us …” like an endlessly repeating riff from a soprano sax player who’s passionately belting it out to the back row.

Today was a good day for chasing rainbows.
A bike with fenders, plus the right cycling clothing, lets you see amazing sights that fair weather cyclists will likely miss.
When photographing rainbows, remember angle of incidence = angle of reflection.

Building bike/pedestrian trails is just the beginning. A bigger challenge seems to be maintaining these trails.

No DSM diagnosis for road rage & bike hate (yet). Closest seems to be Intermittent Explosive Disorder - repeated episodes of impulsive, aggressive, angry, or violent behavior disproportionate to the situation.
In my experience, that describes driver behavior we witness every day!

Every time I see someone with a bike on a BART escalator, it makes me smile - especially this rider prepared for rain.
Not all policy making is so visible & tangible.
Two years after we started allowing bikes on escalators, it’s worked perfectly. I haven’t heard complaints or of any big accidents.

After an hour, my Clipper account migrated. I helped my wife do the same, & she had similar issues.
Her account finally migrated, but she lost her SENIOR Clipper card status. I did not lose my SENIOR card status during migration.
So she just REAPPLIED for a SENIOR Clipper card.
