Personal confession:

One of the reasons am such a jerk about texting and driving is that, when I was 22, I totalled my car doing exactly that.

I've only told this to a couple people.
๐Ÿงต
This was in 2009, i.e. before smartphones.

I was going to frisbee practice and pulling up to a light. My phone buzzed with a text and, as I slowed down, I checked who it was from.

I thought I had space between me and the next car but I looked up just as I crashed into it.
Luckily I wasn't going that fast, maybe 8 or 10 mph. My airbags didn't even deploy. But it was still enough force to crush my car's radiator.

Thanks to forces beyond my control, no one was hurt.
If there had been someone biking ahead of me, god knows how hurt they would have been.

It's the only time I ever crashed a car (and I've never even gotten a traffic ticket), but the result that day was because I was lucky not because I was good.
The car I bought to replace the one I totalled was a stick-shift Corolla, one I literally could use my phone in.
This is why, when I'm in the car with someone and they pick up their phone, I offer to let them dictate a text.

It's why I politely ask drivers to stop staring into their phones (they usually don't see me, naturally).
Pedestrian deaths have increased 50%(!!) in the last 10 years.

It's not clear the exact degree to which distracted driving has contributed to this, but I'll guarantee it's a significant factor.
While there is *absolutely* meaningful and necessary work to do on changing out physical infrastructure, we need to immediately do everything we can to stop drivers from staring at phones while operating multi-ton vehicles.
If you drive a car, put your phone away. If you're in a car with someone using their phone, ask them to stop.

Distracted driving is a the drunk driving of our time, and we can't make our roads safer until we actually decide that it is a problem and try to fix it.

It looks like all of LA is on the 405 right now.

But...how many people is this? And, better yet, how many trains would it take to move them?

Let's do the math.

๐Ÿงต
We're looking at the interchange of I-405 and I-10 in Los Angeles, facing south.

When we zoom out, we see a full view of I-405 from Ohio Ave to Sepulveda Blvd, a distance of 5.8 miles, or ~30,500 feet. Google maps showing aerial ...
The 405 is five lanes in each direction for this entire stretch, plus auxiliary (merge) lanes, so essentially 12 lanes across.

Some quick multiplication gives us 305,000' of through lanes and 61,000' of auxiliary lanes.

This is about 160(!) acres of space in total. I-405 streetview

This is almost *too obvious* to notice, but the reason that paint works to delineate lanes for cars is that drivers *carry their own physical protection.*

They don't need walls between them and other cars traveling in the same direction because their car has walls. Traffic on I80
People on bikes carry no such armor, meaning paint and soft, plastic delineators do not...do anything.

If you don't feel safe in a paint-only bike lane, it's because you're not. Paint-only bike lanePaint-only bike lanePaint-only bike lanePaint-only bike lane
Because they don't carry it, bike users need their physical protection to be part of the built environment.

We need delineation that will *resist* incursion from cars.

This means k-rail, concrete, strong bollards, or putting the bike lane above the curb. K-rail separated multi-use ...Concrete protected bike laneBollard bike lane - Creativ...above the curb two-way bike...

This is the first installment of #NorthBayNotes, Dispatches from Marin County by Bicycle.

The ongoing series will be things I notice, fun and frustrating, exciting and exasperating, while riding around the county I work in.
This is Nick. He rides an electric tricycle and told me he doesn't even need a car.

Many days he rides up to 20 miles, though the battery is good for 50+. He was generous enough to let me stop him and chat. Old man on an e-trike
Work continues apace on the North-South Greenway Gap Closure project, a new bike/ped bridge over Corte Madera Creek that will replace the existing 4'(!) sidewalk. Construction site

Driving works best when only a few people are doing it.

But we've designed a system where driving is pretty much the only viable option.

Raise your hand if you see the problem here.
This is why so much NIMBYism is traffic-based.

People see the traffic we have today and imagine that twice as many people will mean twice the traffic, so they feel they have no choice but to say "no."
Because our traffic engineers have failed to design a system in which people can do anything other than drive, they (perhaps correctly, perhaps not) assume that anyone else coming to their neighborhood will drive as much as they do.

On a zoom weminar hosted by @CalBike with renowned bike researchers John Pucher and @buehler_ralph on international international comparisons in biking!

Here is the share of trips made by bike across North America, Europe, and Japan. Huge variation across countries, with English speaking nations lagging behind.
But these differences are not because those countries are more dense! In the US, our share of bikes used for even short trips are tiny!

Whereas in the Netherlands, nearly half of all 1-2.5 mile trips are on a bike.

6,000+ miles of riding over my three years in the Bay.

All my bikers out there, what do you notice? Strava bike heat map
Super true! SPA is a huge block hole my map. 9th St and California sort of work, but have their own issues (and no fronting commercial for me to actually use!)

I mean, this is the elephant in the room, right?

It's also so striking to see that we can get 2/3rds(!!) of the way there today. It's just not that far from Yerba Buena to Embarcadero, and yet it might as well be 1000 miles.
