The salt extraction pools can reduce the salinity to the salinity level of the input water. The amount of effort needed increases as you approach the salinity level of the input so it isn't practical to achieve the exact same salinity level as the input water. In this case the proposed input water is from the Mediterranean which is not too salty for life.

I'm not sure how much more salty the sea can be while still having a reasonable ecosystem and an also not sure what ratio of extraction pools to sea surface area would be needed to achieve that so I don't know if it is actually practical.

I haven't used a car with one of the speed systems so I don't really know enough to judge hope reliable it is, which is an important factor in evaluating it.

I do disagree with your justifications though. To start with for indicators it is true that sometimes they aren't necessary, in fact with everyone driving appropriately they shouldn't ever be needed to avoid crashes. However people are pretty bad at judging their abilities and habits are a pretty strong effect. So sometimes you mess up your observations but then if you indicate anyway the other road users are more able to fix your mistake. Also by indicating every time you build the habit and are much less likely to forget to indicate when you should.

It is fun trying to come up with situations where speeding up to avoid a collision is needed but in practice this is really dangerous. If you brake to avoid a collision then if the avoidance fails the result is less bad. Any cases where braking isn't going to let you avoid a collision must be situations where you have very little time to react since cars can change speed more rapidly by braking (limited by traction in any vaguely modern car). So the situations where you need to speed to avoid a collision are ones with very little time to process, where you have one known bad road user (since otherwise you wouldn't be at risk of a collision). Bad road users are unpredictable. All these factors make it really dangerous to accelerate into a hazardous situation. Instead you should train yourself to drive defensively and react to road dangers by braking as a first response. Again it is best to build a habit since you have very little time to evaluate and react to these situations.

I agree with you about the shoddy drivers, I don't drive a large amount so I'm aware that my driving skills aren't super high. Because of this I consciously drive defensively, don't drive fast to give more reaction time, leave a larger gap to other vehicles. Having lots of shoddy drivers is a great reason to have speed limiting technology because most of them overestimate their skill and speed. In the UK a large majority of drivers regularly speed and this has a pretty direct link to increased injuries and deaths.

In the UK stop signs are rarely used, they are in places where visibility is so poor approaching the junction that it wouldn't be safe not to stop.

There are definitely places where it isn't safe to roll through a stop sign, unfortunately in the US the system uses stop signs as a kind of traffic calming measure so then there isn't a clear way to mark the places where stopping is absolutely needed for safety. Of course in theory drivers should be able to notice the lack of visibility and drive accordingly but in practice the hazards can be somewhat subtle and many drivers have poor judgement.

The osm.org main site is primarily intended to be used by mappers, not end users. So for this purpose it makes sense to use local languages since most people doing the mapping will be locals.

Other renderings such as the maps with me app use the appropriate names for the users language if available.
