Why do journalists continue to compare American cities to Copenhagen or Amsterdam when it comes to bicycle infrastructure and safety? I argue it is primarily the climate followed by size.

In Denmark the climate is mild, with few hot summer days and even fewer snow days that would make bicycling impossible. Comparing Boston average temperatures to Copenhagen, Jan-Feb on average are 4 degrees C lower and July-Aug are 7 degrees C hotter [1][2] in Boston. Then there are lists of America's worst bicycling cities ranking Dallas, TX at the top, where average July-Aug highs are 15 degrees higher than in Copenhagen [3]. Climate wise the cities are very different.

If you can't bike to work everyday because of the weather then infrastructure of bikes cannot replace car infrastructure. In Denmark bicycle infrastructure can replace car infrastructure because the climate makes it possible to bike work every month of the year. In even mild climate cities like Boston it becomes much harder to be dependent on bicycles with hotter summers and colder winters.

That's looking at the climate. Next, the Boston Urban area is 4.600 sq km with 4 million people, whereas Copenhagen is only 606 sq km with 1.6 million people [Wikipedia]. Some back of the napkin calculations would make average travel distances 3 times greater in Boston.

Because of the differences in climate, size and population between Copenhagen and Boston, I do not consider bicycles a viable solution for Boston's transport challenges and I extend this line of thinking to most American Metropolitan centers.

I need to ride up a hill that even my car has problems with. There are many more similar hills in my city (around 1.5~3 million people).

Have you ever used a 250w ebike? They are incredibly powerful and they also come with gearing much lower than cars. The power on an ebike does not limit how steep you can go. I took a 250w ebike up a path so steep I had my chin on the handlebars to stop the front wheel lifting off the ground and the motor was powering me up fine.

I did, I had to pedal the exact hill I'm talking about and it definitely wasn't easy; I sweat through my suit because of that. Sold (back to the shop) the bike the next day. Instead of it I got an illegal chinese e-scooter that has 800w and is just perfect in every way. Never had a problem with the police, btw. Sadly I had to give my business to a Chinese supplier instead of local.

I appreciate a lot of the ideas of accommodating bikes, and think it's a laudable goal. But it's not practical everywhere. As an example, I have lived in Houston in the past for some time. It is huge - I commuted roughly 20 miles each way. That's not "bikeable". And not everyone goes to the same place. Some work downtown, but not nearly as many as you'd think. The energy corridor is in an entirely separate area. Many…

You're completely right, most cities just aren't built for cycling. The solution is probably zoning. First, create smaller zones, resulting in more diversity. Second, allow some light commercial use inside residential areas. Ideally, stores like small supermarkets should always be within a 20-minute walking distance inside towns or cities. Third, create denser plots: discourage single-story buildings, leave less spac…

Shortening the distances is not enough to solve the heat problem, when being outside 5 minutes with moderate motion resulting in needing a shower.

Agreed - details matter a lot. For example many years ago, Camden in London put in green asphalt cycle paths - one was dangerously hilarious - you ran parallel to the main road, on a painted strip, on the side of a one way street - going against the traffic. However the new cycle "superhighways" in London are a big improvement but oddly now I find the biggest challenge is to change the attitude of the cyclists - we h…

Sorry to be the annoying guy pointlessly arguing semantics, but how can it be a "superhighway" when there are lights blocking traffic? Projects like that would be just as much of an improvement without the deceptive branding. To me, it's a sign of disrespect: give them what they want, but mock them with exaggerated naming.

Highways can have lights blocking traffic in the UK, is there a different meaning in the US?

Superhighways and quietways are being merged and rebranded Cycleways soon.

Because they're the world leaders and something to aspire too

There is one terrible issue I encounter almost every time I ride to work. In the mornings the traffic is stopped all the way to work. The stopped cars leave gaps next to the side roads so cars coning from the other direction can turn across to reach them. Because there is a wall of cars in between the bike lane and the other side of the road, neither the turning car or I can each each other so the car blindly turns a…

Seems a reasonable assumption to me. If someone is waiting to let someone else pull into a sideroad shouldn’t you wait as well? It’s dangerous to overtake on the passenger side regardless of what vehicle you’re using. You should overtake on the driver’s side so people can see you easily.

I can't see if anyone is turning because cars leave a gap when no one is turning so if someone does show up they are able to turn. Also I don't think overtaking on the drivers side is allowed on a bike.

How would you handle locations where cars are turning right and cyclists are riding straight?

Note: right turn on red is illegal in all examples. Like this: https://goo.gl/maps/HJnyxbs1hnJ2 https://goo.gl/maps/VatZztEiXTJ2 https://goo.gl/maps/PpSaGeChwS12 Note the advanced bike stop line. https://goo.gl/maps/zJZNRTYQ5ZL2 Note the bike-only tunnel. https://goo.gl/maps/CWLmL1DTsBs https://goo.gl/maps/dGJSZnQVfw82 https://goo.gl/maps/rvf9hP3DvV62 https://goo.gl/maps/sYNKHgEBsZk Note the two-way left turn for cyc…

All of those intersections look great. Treating bicycles and cars as totally different streams of traffic certainly works in those locations. It would be a major change in other locations in other nations.

If "not grossly negligent" is the standard to which we're holding drivers, I don't really see the problem with the "X-crossing" displayed in skookumchuck's sibling comment. It's very clear that right-turning cars have to cross the bike lane to get to the turn lane, and any bicycles in the bike lane would be quite evident. Realistically, we can expect some automobile operators to do the wrong thing at that intersection, but that would be negligence.

> zoning

Interesting point, as Houston currently has none. Arguably good for growth and business, though.

> smaller zones, resulting in more diversity.

Not sure I understand this part. Diversity of what? How?

> allow some light commercial use inside residential areas

This will be harder to deal with than it at first seems. Due to the earlier-mentioned lack of zoning, many neighborhoods have HOAs.

> discourage single-story buildings

How?

For what it's worth, I'm not sure I like the sort of cities that are considered "bikeable". Houston was nice in part because it was so open and wide. There was lots of green space everywhere you looked. Compared to cities like NYC, I'd argue Houston looked a lot better. Many more "sprawling" cities have much more pleasant, open atmospheres , rather than the dull, lifeless cement that pervades every inch of many other cities.

> narrower roads

Not sure this is a good idea. Many people in Houston own larger, comfier cars. A lot own trucks. Not all need to, but some do: many people have ranches, and Texas is so big that there's a lot of driving. This means a bigger car is sometimes necessary to fit enough stuff. It can also be nice when you have to sometimes do almost 250 mi day-trips.

On the heat issue, you need a shower after being outside and at all active for any significant length of time. Let's consider water usage: How much water would all those extra changes of clothes use? All those extra showers?

And now to the single largest issue: flooding. Remember hearing about Hurricane Harvey? Flooding is getting worse because of denser stuff. I know many people who have been flooded by storms that wouldn't have flooded them ten to fifteen years earlier.

Smaller zones? Denser plots? Less space empty? All of these will cause people to die the next time a storm hits. Many people are already discussing increased permeability requirements for this exact reason.

All of this comes down to the same root issue: many people simply wish to force all cities into a mold they believe works for theirs. There is a very "coast-centric" view in many places, new urban planning trends are premised on cities like SF, NYC, etc. Cities with decent weather, no flooding, a central commute destination, etc. It's worth rethinking how to do this for other cities that don't conform to the mold of coastal cities, because trying to force every town into that mold is impossible to do well.

Exactly. Many people don't realize that Houston is not just hot but humid. How much water would all those extra changes of clothes use? All those extra showers?
