In the U.S. we're struggling to get them to understand that bike lanes and sidewalks can't just randomly end mid-block and still be useful. While the idea seems ostensibly solid, and cars very much need containment, we still have much more basic needs before we can start optimizing car infrastructure.

No, we can start improving car infrastructure right away because, on the types of roads that have guardrails, cars are like 98% of the traffic or more. And the rare roads that have both guardrails and sidewalks should probably have the sidewalks on the far side of the guardrails, at which point improved guardrails also protect pedestrians. Purely from a safety standpoint, outright prohibiting bicycle traffic on motor…

> cars are like 98% of the traffic or more

They didn’t always. That infrastructure was built and subsidized so they were used.

> Purely from a safety standpoint, outright prohibiting bicycle traffic on motorized roads would be a massive improvement at the expense of inconveniencing a small minority of people

Purely from safety standpoint, making less motorized roads would be a massive improvement and people would conform to new modes of travel just like when cars and interstates were introduced.

No, I'm comparing America's car culture to a rat infestation; something that causes serious problems and is a problem in its own right. This has nothing to do with the moral standing of individuals drivers...

Which is a ludicrous, fringe viewpoint that verges on trolling when you go out of your way to bring it up in a discussion about safety barriers for motorways.

Your creating safety barriers for another problem though which are car speeds that aren’t regulated enough, and human and vehicle errors.

Hydroplaning below 80 km/h ~49 mp/h is rare and the risk of the wheels loosing contact to the ground increases with speed. So not sure if this was really hydroplaning. As a tip for others: If you ever encounter hydroplaning make sure not to keep your steering wheel straight (or at least: know why you are doing what you are doing) and step off the gas pedal. In hydroplaning your wheels don't have contact with the road…

That was a mistake
