The only road legal headlights (not only headlights, but all exterior lighting, plus many other technical requirements generally) are those, which are certified to meet the related technical standards. So any external lights not certified to meet these standards becomes illegal on roads.
And in most of the civilized world this is really enforced (technical inspections, roadside police force,...)...

Especially problematic for an aftermarket HID's is the requirement of headlights with low beam above 2000lm (HID's are about 3000lm, while halogens are around 1500lm) that includes advanced glare control (dynamic leveling,...), what means the headlight system needs support from the rest of the vehicle (manly suspension sensors plus the related ECU,...).
And that means practically no HID's could be ever made to comply to the standards without major car system update (cost would become in the few k$ range, plus the development and mainly the certification expenses in the range of 10's k$ (separate certification is needed per each car/headlight type combination).
So that means the only HID's viable for road use are those originally installed by the car maker - there the exact design is implemented on sufficient number of cars, the development and certification expenses could be "diluted" to become low enough to be at least somehow acceptable. And the cars are designed with that system from the start, so the system becomes not that expensive either.

The only function where the HID's could possibly be made road legal without the dynamic leveling are just the high beam. But using HID's just for high beam is not that viable upgrade at all, so the related market would be too small to justify even such simpler certification (the dynamic leveling response is, what makes the design and certification for low beam so complex, so expensive).

They are illegal here as well but rarely get enforced. It is frustrating when you get dazzled by headlights on an oncoming car which turns out to be standard reflector optics with HID retrofits installed.

If I was to upgrade my headlights to HID I'd use 4300K which is a nice, crisp white light for headlights compared to higher colour temperatures.

But routine inspections don't solve the issues either, people just put in there regular lights before taking in there car, and once they are done they just put the HID / LED bulbs back in, the police really just need to pull over the people who have glaring lights, ticket them and tow the car so they learn, and they can tow it if it's not road legal.  But issuing photo radar tickets is easier. Plus while doing photo radar duties they get to sit there playing on there phone all day long ( at least that is what the cop does that parks in front of my place does all day / night long, yes they basically live there issuing a ticket every 45 seconds on average and updating facebook just as fast)

On the flip side it's also not hard to install proper projectors with the higher power bulbs so they actually have the correct optics and they are much nicer then stock lights and if your willing to go the DIY route it's not even that expensive and if your careful they also look great..

Oh they're illegal in the US too, but the enforcement is poor. Some states, including South Carolina, don't do vehicle inspections of any kind, so you can get away with a lot.

Here the government completely banned the HID headlights. HID headlights are only legal if they are original of the vehicle manufacturer and has passed the licensing tests, because of their glare.

Me personally, I have no issues with any fluorescent lamp that's halophosphate or triphosphate. Actually, I don't have
an issue with pretty much any lamp color besides most of the lights produced from LED's. Now when we go passed 8,000k
in color temperature, that's a different story... 8,000k-12,000k (and higher) car headlights and fog lamps are ABSOLUTELY stupid
to me, regardless of whether they're LED or HID. I've seen some cars and even a couple motorcycles with them and I think
it's stupid. I'm pretty sure 10,000k and above is illegal.

I had no problems with the daylight halophosphors 36W T8s we had in the storage of Carmel hospital, before we moved to daylight triphosphors 28W T5s.

Anything in the wrong environment, like 2700K in a workshop or 6500K in a bedroom. I also don't like anything over about 4000K if the space isn't well lit. An exception would be clear MV lamps for street lighting.

Like Mercurylamps, though, I think CRI is more important than color temperature. I'm not a huge fan of the way spaces look under halophosphate Cool White fluorescents, for example, even somewhere like a storage area.
