  • But why even jump to that conclusion? They could have said “may cause baldness”, too.

    I mean, they come up a list of things, but proved none of it: “Chemicals in everyday plastics may disrupt the body’s natural 24-hour sleep-wake cycle and circadian rhythm in a way similar to coffee, which increases the risk of sleep disorders, diabetes, immune problems and cancer, new in vitro research shows.”

    I just wish that journalists would be a little less sensationalist with stuff like this. Even if it were an animal-based study, assumptions should be tempered when it comes to reporting on the implications to human health.

    Not to criticize the study, since we really do need to know how these plastics are harming us, but the headlines need to chill out.

    Can’t acoustic bikes also reach 20-30 mph? I know it’s easier to reach those speeds on an ebike, but is it truly not an issue with regular bikes? To me, it just seems to unfairly target ebikes when regular bikes can also reach high speeds.

    Unless someone is flat out sprinting, those speeds on a regular bike would not be easy achieve by a regular person in a crowded park.

    That said, this is going to be a case of “a few will spoil it for the many”.

    Without electric options, the city would be hurting accessibility, so that would be bad.

    Sigh. I don’t know. Fine people being dangerous? Publicly shame them for riding like an asshole? I would try anything before removing micromobility from a public space.





  • I’ll respectfully disagree, because there are plenty of studies that show a wide gap in understanding of road signs, with some being considerably more intuitive to understand than others.

    As an example, have a look at the data below:

    As you can see, the “no powered vehicle” sign (red line through it) was understood by nearly everyone, with no confusion.

    Compare that to the “no cycling”, “no pedestrian” or “no motor vehicle” signs below:

    You have mass confusion, with very few people actually knowing what the sign means before they are trained. To me, that’s a design flaw.

    Other studies show a similar pattern.

    This one for example, asked people from different countries to identify the meaning of various traffic signs.

    I will point out that the ones which scored nearly perfectly identified, are the ones with a line through them; Signs with just coloured circles were very often misidentified, or understood as having the opposite meaning.

    We can go back and forth on this (I don’t want to), and while I do agree that education can reduce the chance of a sign being misunderstood, that misses the point completely.
