You see more bikes in Cambridge MA than you did before a lot of the bike lane work (probably intermixed with some changes in attitudes/preferences). But still a tiny fraction of both pedestrians and cars.
does us even have a network of protected and optimized bike lanes+comfortable parking for them ? If you can't let a child drive alone in that lane, it's not safe. The point of bike infra in NL is that it's generally safe, many shades for hot summers, semaphores autoswitch when bikes approach to give them green, there are lot of bike parkings and bike routes are shorter compared to car ones, as result you'll get to dest same or faster compared to cars. As result, ppl prefer to use a bike even if car ownership in NL is pretty big(cars are mostly for long trips for routes where pub transport is not that good). Does US have anywhere same lvl of bike infra(or even close to it) any any existing city?
there's not a single city in the US that has a real bicycle network
despite all the improvements even cities like NYC still doesn't have this
imagine a city that's made up of a neighborhoods with high quality roads inside them but unconnected and separated by patches of sand dunes or dirt fields with between them
would you look at that and conclude "nobody drives here, these people must hate cars, we shouldn't invest in roads then, roads and cars are a useless technology, hiking on foot or riding a camel or donkey is superior!"
of course you wouldn't
but that's exactly what it's like being on a bike in ALL cities in the US - islands of a few (mostly unsafe) bikeways here and there, but not a complete, safe network to connect them in a meaningful way, so it's little wonder they're not as used as they could be (although despite that, esp in nyc, bikeways ARE heavily used)
if you wouldn't ride in them, they're not safe
if you wouldn't let your kids or nephew johnny ride in them, they're not safe
meanwhile in the Netherlands, Valencia, Seville, Barcelona, Paris and a bunch of other places in the world, they HAVE started to build meaningful, safe bikeway networks, and what do you know, then, tens of thousands, hundreds of thousands and millions of people (including families and kids) end up using them daily
taking cars off the road and freeing up space for ardent motorists who always complain about traffic
it's a win win but most motorists are too blind to see it
