I think that is much more damaging than one person getting 4 kids dead, as much as this is already a tragedy.
Going with this reasoning people should be banned from using cars at all, because, frankly, I see a huge number of people driving completely irresponsibly and not thinking a whole lot about it until an accident happens.
Do we really want to live in a world where it is not possible to behave irresponsibly because all options were taken off the table?
I lived in Singapore for a few years and that pretty much is that world and I was very happy. Don't really see the problem with banning things that people cannot stop to use irresponsibly and that cause loss of life, including cars. (well technically they're not banned, a license is just hard to get, 10% or so own a car).
Build good public transport, walkable cities, done. I mean have you actually considered how mental it is that we let people roam around in two tons of metal at high velocity next to pedestrians just to buy a bag of groceries. If people look back at this in 500 years we'll look like crazy cavemen
Does this ultimatum still make sense?
Here in Poland people just started bringing their own EDC knives.
No, I believe in banning things when the vast majority use them irresponsibly.
That demonstrates that it's just not something we're capable of handling.
But it would kill the industry if it was enforced now, so I hope we will get it later once people actually got the taste for it and want to continue using them even if they need to get a licence.
I don't care for the "industry". They must adapt. Driving car requires license but the industry is still there.
The Dutch police could make a good revenue just from targeting food delivery guys. Excluding the newer e-bike delivery people, they are almost always speeding and driving like they just robbed a bank.
If we are both of equal size and mass, the damage will be approximately shared.
But my comment is this: 20MPH is fast. The damage is grievous. Dead or nearly dead.
Add in pedestrians - 2mph and now what? Its a hard problem.
That means the bikes, cars and pedestrians are already separated.
The mopeds/scooters (who go up to 45kmh / ~28 mph) are the only ones who don't fit in. That why they're constantly switching between roads, bike paths and sidewalks.
Scooters are "more different".
Both require insurance and an 'insurance plate' which is a different format from the standard licence plate seen on motorcycles. The rider must be licensed, but this can be either a car or a motorcycle licence (or a moped-specific licence which can be obtained from the age of 16, compared to 18 for cars and motorcycles).
The 'snorfiets' scooters have blue number plates, and are legally supposed to be limited to 25 km/h. The rider does not need to wear a helmet.
The 'bromfiets' scooters, with yellow number plates, are legally supposed to be limited to 45 km/h, but the rider must wear a helmet.
(In practice most scooters seem to routinely go much faster than they are supposed to be capable of)
In general, both types of scooter can use some, but not all, bike paths. A snorfiets is allowed on more bike paths than a bromfiets is- bromfietsen must ride on the main road in built-up areas.
Whatever rules exists here exist on paper only.
Its a hard problem to solve.
We just can't solve it for cities because people have their heads up their asses and everyone wants their preferred class of traffic to get preferential treatment.
But rules and people don't get along that well. Folks get tired and impatient. Even in the industrial environment there are expected failures per 100,000 hours etc.
Still, agreed we'd all do better with a more professional class of driver and licensing.
Outside NL, the "step" is a scooter, and the "scooter" is a moped.
Mopeds should be banned from bike paths, or there should be heavy enforcement of speed limits on paths.
A little folding 2 wheel platform vehicle going 16kph is certainly no worse than a large Dutchman riding the same speed on a 35kg omafiets... not to mention the person on a 40kg electric bike who is doing 23kph.
A light bike doing 16 kph will knock you down but not seriously injure you unless you're unlucky.
Mopeds are doing more like 16 mph (25kmh) and easily weigh 70+ kg. That's a fast and heavy chunk of metal. If that hits you, you will be badly injured or killed. That changes the stakes of the bike paths from scraped knees to death or brain injury.
I very much do not want motorycles or mopeds or even fast electric bikes (which can weigh nearly as much as the rider) on bike paths. A scooter/step weighs about 15kg, and more importantly, most of its weight is very close to the ground. It might knock your feet out from under you if it hit you, but it won't crush your ribs or head unless you're already lying on the ground.
The vast majority of them drive completely irresponsibly. They go at least twice as fast as the bikes on the bike lanes so they're constantly going in the middle of the lane into oncoming traffic. I've lost track of how many times I've had to swerve on my bike because someone comes right towards me.
The Netherlands does not actually have bike lanes. It has shared moped/scooter/bike lanes.
