"Use bicycle bell!" Lund's solution to their own horrendous planning. Four lanes for cars. Cyclists surely sort out who'll get the first try to not get stuck in the fence with their handlebars. Pedestrians are expected to dissolve. In which way exactly does the bicycle bell help here?

Som cyklande bländas man av biltrafikens belysning. Särskilt påtagligt när man cyklar mot biltrafiken på en dubbelriktad cykelbana som ligger nära körbanan. www.sverigesradio.se/artikel/cykl...

Cyklister upplever att bländande biltrafik har blivit ett allt större problem. Det visar en studie som just nu genomförs av Statens väg- och transportforskningsinstitut.Enligt ...

Det tål att sägas igen. Omkörningar av cyklande ska ske med ett helt filbyte. Det borde vara en självklarhet att man gör allt för att inte skrämma och hota andra människor som befinner sig i ens närhet. Det är varken coolt eller starkt att utnyttja makt.

One almost wonders which transport mode has an engine. One of a thousand examples where bikes cover more altitude than cars. And often there are steep ramps. But hey, we're cycling for exercise, right?

I so wish that tyre and engine noise would be heard inside instead of outside of the vehicle. It's gruelling and mind-numbing to ride on a "perfectly safe" bike path next to a road full of cars.

Not quite sure. It's rare to see cars share space instead of dominating it. The non-car user mass would have to be really big compared to the car volume if cars are to behave subdued enough to consider it sharing.

On Saturday I learnt by experience what an impact at 30 kph means for the body. I assure you, it's not pleasant. It appears cynical to think that this is an acceptable speed to hit people with cars.

Bikes on trains in Sweden, episode 443981: Going from Linköping to Emmaboda over the weekend, around 250 km. Without bike: 1 change. With bike: 4 changes. Obviously no guarantee to get the bike onto the train. Already 4 bikes on the platform. Taking an earlier option just in case of failure.

Yes, and this isn't something where a "compromise" is going to make sense: "You can keep your unjustified privilege as long as you only hurt us less than a lot."
The negotiations we're forced into:
The world: Cars everywhere!
Me: Ban cars.
Ok, now that we've voiced our opinions on how urban infrastructure should be allocated, we can start to negotiate.

How cynical is this world where one can kill children with cars and this is accepted as normal ("nothing wrong"), but where the killed child's parents get charged for letting their kids be "unsupervised" in public space?
This is where we're headed every time we discuss wearing hi-viz.

Bikes on trains in Sweden, episode 443765. Two more wanted to get on. Would have been easy any other time. This time conductor refused on a whim, saying max one more. Next train cancelled. One hour to next train after that. Sustainable travel in Sweden, just forget it.

It shows how deeply rooted carbrain is in our society when even the left side of the political spectrum considers it "necessary" to make public transport users instead private car users pay.
Raising already high prices for public transport. Meanwhile car drivers are laughing with fuel subsidies, free parking, and free access to the center.
Just burden the drivers a little and kollektivtrafiken will have enough funding, space, no delays in car queues, etc.

To follow up on this - had written a proposal to the annual meeting to take away the free parking for cars. The steering group opposed that, and the annual meeting voted against it. Unfortunately I could not be present at the meeting. Very disappointed by Friskis & Svettis Linköping!
When your gym asks you to sort plastic bottles, because they ❤️ the environment, and at the same time let people coming by bike subsidise car drivers' parking. While not even providing any proper bike parking. Carbrain forever.

In a conversation about transport politics today, the other three agreed wholeheartedly how bizarre it was when a transport politician or planner didn't have a driver's licence. But did anyone of them discuss whether they'd have to be cycling? Scootering? Even walking? (Spoiler: no.)

Sustainable travel in Sweden: Trying to get myself and my bike from Linköping to somewhere outside of Borås. Train takes forever (and they don't really take bikes). Bus (Vy) says on homepage they don't take bikes. Solution: 4 regional trains (4 h trip), then ride 50K. Amazing.
