There's a big problem with "car blindness" when it comes to cars, pedestrian crossings, car signs I think we forget how invasive they are.

So instead, I want you to imagine the sea or a very large bay, the most wide open space available, then I want you to imagine a ferry that can carry 500 people, big yes but there's still plenty of sea and its reasonably tranquil.

Now imagine 500 people on jet skis roaring around, then imagine that the jet skis and ferry are all trying to get somewhere different but that's relatively the same, perhaps commuting between the different sides of the bay.

If I was mayor I would put a stop to 500 jet skis and say look you have to use the ferry, people on jet skis keep colliding with each other, the noise is horrendous for people on the beach and makes swimming dangerous, and it's also wildly power inefficient when you step back - that's even if we ignore the pollution! 1000 spots to store a 500 jet skis on both sides of the bay is perhaps even worse!

If you can make a sea packed and grid locked with just 500 just imagine what it does to a city with thousands, hundreds of thousands, if you then turned to me and said the jet skis drive themselves! I would still think most people should be taking the ferry and there's a upper limit to sustainable jet ski use.




The ferry is not originating or stopping at every possible destination on the shoreline, so the ferry is only useful if its passengers 1. have a second way to get from their origin to the ferry and a third way to get from the ferry to their destination. And if the ferry does stop at every possible origin and destination along the shoreline, then it's going to take much longer on average than a point-to-point jetski.
