In Israel, many lampposts have got knocked down by 85km/h (52.82mph) winds. One of them in the south Tel-Aviv, falled onto a car and totally disintegrated it into pieces.

With all that rust it can be expected

First imho it is better to install poles with the base plate above the earth. This way the pole never touches the soil (which contains minerals that cause the corrosion)

Second is the material quality in this pole ok ? Maybe the plating was not done to well

And if there is a known problem why not use sacrification electrodes to protect the poles

Indeed. But isn't the base above the ground, will block the sidewalk. It must be wide to allow balance for the lamppost.

If there is any plantation area along the sidewalk then it could be put there. Otherwise there i a problem

Dor and Ash

Both of you make a good point. The first thing I noticed was the rust, yes base plate above the ground is the solution. Many in Australia are now installed this way, it is not very intrusive. I feel bad for the car owner hopefully was not hurt.

Blake: The car was empty when the pole hit it, and there were no deaths or injuries at this event.

It is a typical oxide gradient induced corrosion. It corrode only few inches below the surface, because there is higher oxide concentration in the soil. It create a galvanic cell (metal deep in the soil with low concentration become a cathode, the part just below the surface with high oxide concentration anode and this anode dissolve quite quickly).
The only known cures to improve the lifetime are either make the pole wall thicker by adding an outer metal layer, so it take longer before it get consumed, and/or using concrete (non-metal) "pedestals", so the metal isn't exposed to the surface soil.

Some makers put thick layer of an epoxy around the section, what is supposed to be in the affected area, but I've seen installers to completely bury this section, so it became useless and such pole installed in that way disintegrate way sooner than predicted.
What seemed to help was having one tube ending just above the surface and the main pole then stuck into that tube and then seal the area between them by something not conductive. The fence poles I made this way (originally in order to be removable) survived for more than 3 years, while the ones made in an ordinary way usually disintegrated after about a year (I used already rusted scrap-grade tubing for all of that, as the fence was a frequent target for metal thieves)

The galvanization layer is nothing else than a form of (an integrated) sacrificed anode, but quite a poor one. But I'm afraid the oxide gradient is so strong, than it would eat up the coat in few months there, so it is not as much a protection for that case. Due to the same reason, the external sacrificed anodes won't be as efficient either.

In any case the pole have limited life (the design with no protection means, beside the galvanization and paint, look for no more than 10 years life rating) and usually it does behave exactly as the engineers have calculated (assuming the installation was made correctly). But the city councilors tend to order 10 year poles because they are the cheapest and after the 10 year passed, they even do not carry the extra inspections and repairs the safe operation of such overaged equipment need...
As a result after 25 or 30 years they (the newer generation) are surprised, why the pole collapsed. And as a replacement, they order a 10year life rated pole again, because it is the cheapest one...

Most of the lampposts in Israel, are installed without base plates.
All of the Philips Triangels (And lampposts at all) in Kiryat Benjamin neighborhood (Where Lilenblum street located), Kiryat Ata, mounted directly on the ground, without base plates.

They do have base plates - only very few are of the "continuous pipe" type, usually cast iron decorative ones. The plate is below the earth surface and this is he cause of all problems
