I've bike commuted to work. In a very bike friendly area.

Everyone I know has been in an accident of some sort. Hit & runs, side swipes, doored, pushed (deliberately), etc.

After better infrastructure, the most effective way to improve safety is to have more cyclists. I think we're in a rough transition period, but things are definitely getting better.

One of my bike buddies thinks things will really change once moms start cycling en masse. That'd change the perception from gonzo bike dudes to totally uncool in a heartbeat, evoking much less hostility.

I live in the Netherlands (16 million people, 23 million bikes). I went to San Fransisco a few months ago, one of the most bike-friendly US cities from what I've heard. Riding a bike there made me want to make sure my will was updated.

Biking in the US is way more dangerous than in countries where it's more popular, like the Netherlands.

I have several coworkers that have stopped biking to work here in sunny, liberal SF because of near-death experiences commuting on a bike.

These are both avid riders with professional-grade equipment taking a short Mission-FiDi route.

Regardless of its "project zero" marketing, SFMTA has bikes last on its priority list. It has to be pushed by guerrilla infrastructure groups to do anything meaningful.

In some areas, it is quite dangerous due to a lack of bike infrastructure and the driving habits of locals. My ex husband sometimes commuted to work by bike and often bitched about this.

I live in an area with good roads, good cars. We get a bike fatality a few times a year. At dusk I find even the well-lit bikes a little hard to discern. We also have some bad drivers. In the most recent fatality the lead rider of a bunch riding on a road was decapitated.

I used to ride bikes all the time as a kid but I would not make a habit of riding on our roads. It's too much of a gamble.
