Cyclists travel at speeds they can easily slow down or stop if some blind person walks into the lane, sighted people do it all the time anyway. The typical long sight lines give plenty of time for a cyclist to spot someone sporting a red and white cane.
“We don’t have any evidence at this time that there is an injury collision problem."
Note: this is copy/pasted from my comment on the Nebula version. Time codes might be slightly off.
The stock clip used at 3:20 involving a driver unabashedly on their phone is brilliant.
The 5:45 clip of a dude in a bigfoot costume cycling through Tokyo was unexpected.
6:00 the self-shout-out had me laugh out loud.
The idea of lowering local street speed limits not actually making your trip take much longer is so true. Brisbane-based cycling safety advocate Chris Cox has a video where he gives a demonstration. He drives the same route twice, once sticking to 30 km/h on the local streets, and once trying his best to get up to the speed limit of 50 km/h on those streets. (Driving to the predominantly 60 km/h speed limit on arterial roads.) The video on the whole is actually incredibly similar to this one, down to the safety/speed curve, the FOV comparisons, and the dismissal of the ridiculous arguments against 30 km/h. Because yeah, Jason’s words in the conclusion to this video are so right: the data is really, really, really clear here; at some point we have to realise that anybody fighting against lower speed limits within cities is either wilfully ignorant or they’re a selfish arsehole who values their convenience more than other people’s safety. But here’s a timestamped link to the bit of Chris’s video where he starts his experiment. It took a whopping 9 extra seconds. 9 seconds, on a 10 minute journey.
To ensure compatibility, you said you had a local bike shop… you should probably go there and get your brakes swapped with whatever you’re excited for, that they can order in.
I’d also recommend a book I checked out from the library recently, Emergent Tokyo, which goes into a lot of the same subjects and has some great insights.
Towards the end of the video he addresses the point that the optimum speed of cars is around 60(or I thought it was 70).
This argument doesn’t apply here because that figure is for a car traveling at a constant speed on a straight, flat road with no wind. E.g. a freeway/motorway. In a city, a significant amount of the energy is used to speed up and slow down at intersections.
Remember the kinetic energy formula, Ek=1/2 mv^2 . That tells you that accelerating a car to twice the speed takes 4 times the energy, or in other words it takes 4 times as much fuel to get to 60 as it does to get to 30.
This extra energy to get up to speed is going to far outweigh any benefit from less rolling resistance at 60 compared to 30.
fwiw, Lemmy actually supports both subscript and superscript, though the syntax is a little weird if you’re used to Reddit. ~text~ is subscript, ^text^ is superscript. (Unfortunately support on mobile clients—even Jerboa, made by the official Lemmy devs—is rather lacking.)
Ek=1/2mv^2^
But yeah, that’s a really good point. I wonder how long you’d have to be travelling at 60 km/h to make that extra acceleration worth it in terms of fuel efficiency.
As a separate question: people would probably often be willing to sacrifice their fuel efficiency if it meant substantially shorter travel times. I wonder how much this would actually work. On highways it’s definitely going to be a huge factor, but on the sorts of inner-city stroads that are usually posted at 60 km/h, I suspect you’ll probably arrive at most of the same red lights accelerating up to 40 km/h as someone getting all the way up to 60 would. Would be an interesting experiment to conduct.
Ah, that explains why the auto-suggested title didn’t work here when it did work in !nebula. My damn mouse has a habit of double-clicking when I use the button I have set to paste.
The only difference I see is instead of crossing a highspeed car lane, one would cross a slow speed cycling lane designed with the intent to protect individuals on bicycles.

This only goes decently for cities. Plus in the Netherlands prices have been going up and up and up. It’s not fun anymore and it’s cheaper to take the car.
So you don’t have taxis driving on sidewalks or motorcycles speeding down the wrong side of split avenues and you STILL have about the same road deaths and injuries per pop as Taiwan?
When I was shopping for brakes, years ago, lots of told me SLX has all the quality/power of XT or XTR but they’re a tiny bit heavier and don’t have the prestigious badge. I went with SLX and have been very happy.
