A big problem is bright screens and displays inside of cars at night. Your night vision never kicks in so you need extra bright lights to see, thus these bright lights that only light up a small section of the road. The more dispersed and even lighting of the old lights is so much better.
I don't like my wife's car for several reasons, but one thing it absolutely nails is the dash: all the lights are orange. It's a night-and-day difference (pun intended) to most cars that have blue lights everywhere, plus an LCD screen in newer models.

If you are using low-beams and driving more than about 45 mph, you can hit something (or someone) before you had time to see it (or them). Granted, that doesn't matter if you're following someone else, since they'll hit it first. Which is why you need high-beams on when there isn't someone else around to light up the distant part of the road for you--and which depends on how often you drive remote roads.
If my comment was interpreted as some advocacy for the removal of high-beams, please allow me to correct the record: I think they're a good feature to have.

My observations from the UK, formerly almost 'Europe': Boomers need cataract operations! A huge part of the car dependent population are elderly. These folks need ten times the light to see anything when compared to the seventeen year old learner driver (that doesn't go out at night, because their driving instructor clocked off hours ago). My thoughts regarding this are somewhat anecdotal, however, I have heard a mys…
Where do you get your data on flat tires? I get flats in a car every couple of years or so and not from potholes but from the screws and nails. How a pothole can even puncture a car tire in principle? It's not a tubed bicycle tire where you can pinch inner tube with the rim. As for "missing" spares - all cars without a spare I owned were using run-flat tires, those are better than a typical "doughnut" spare when flat…

I do this on long drives, but always have to put it back to normal when it's time to park. It would be neat if cars would implement some sort of automatic switch between this configuration and the straight-back mode when reversing.
Why do you need to see the sides of your own vehicle to park ?

No shoving sensors required, the data is all in the ECU accessible over OBDII interface. The car knows if it’s compliant in real time using the sensors it already has.
Wouldn't the VW dieselgate show that we can't trust the manufactures? A third party sensor would be more trustworthy to me.
A 3rd party sensor would be incredibly expensive for inspection stations to purchase as it would need to meter the air and fuel which enter the engine (assuming we aren't going to trust the car's computer which already knows these figures) as well as to measure the emissions out of the tail pipe. This is economically unrealistic to implement without a dramatic price increase in the cost of regular emissions testing.
Trusting the computer is the economical and realistically widely implementable solution. But yes, it has it's blind spots.

Tangential - in the case of low profile tires, I've seen pothole damage where the rim itself was broken. That causes a "flat tire" even if the rubber tire itself survived.

I explicitly stated that my experience is from UK roads, not American. Our roads go back to Roman times, yours date back to Henry Ford, give or take a century or two, kind of brand new, when compared.
Let me describe the last 'puncture'. Car: Toyota Yaris, three occupants. Road: narrow not-even-B road. Pothole hit at roughly 30 mph. No air in tyre shortly after that.
You could witter on about whether this was a puncture or not, all I know is that I was the one crawling in the mud, swapping to the emergency spare tyre in falling light conditions, with one of those stupid scissor jacks that just wants to buckle and bend.
In the UK run-flat tyres are rare on new vehicles and even rarer on second hand vehicles. Winter tyres are also rare in the UK. Maybe we are just cheap in the UK, not needing to haul untold un-metric tonnes as Americans spend their time doing, and not needing to go at 155mph plus as Germans spend their time doing.
As for bicycle tyres, I am not riding for 'conspicuous leisure', which is the American way. Normal tyres with some puncture prevention layer in the carcass works for me, until I get that first puncture. When I get that second puncture, I take that as my cue to replace them, since it is the carcass that has gone, with the puncture prevention going too.
The fashion in 'conspicuous leisure cycling' is for lightweight 'tubeless' tyres filled with sealant that has to be replaced every few months. The idea is to have lower pressure, wider tyres for better rolling resistance. Allegedly these miracle tyres solve punctures, yet people with these tyres go to the local bike shop on the regular, which is not an option for me, since I need my bicycle.
Hence I use normal tyres and tubes, with a track pump by the door. I keep them inflated to the value written on the sidewall, which means relatively high pressure and minimal carcass flex, thereby keeping them good for longer. My goal is to get places with safety and ease, so it isn't about 'conspicuous leisure' or keeping up with the latest trends.
Weight also comes into it, and force = mass * acceleration. As a 'stick-man', envious of those with visceral fat, never in a race to get anywhere, always on rock-hard tyres, I don't get 'pinch flats'.
Anyway, I am off to do some plant buying, to see what fits in the panniers. Hopefully I will be back with some lovely new house plants, riding back with a mini-forest, which will be 'conspicuous leisure cycling' of sorts.
Keep on riding, your own way, and come to the UK some time to enjoy the wonders of our National Cycling Network, taking trains as needed. I am sure you will also enjoy studying the automotive curiosities that the car dependent have over here too. American car culture is far more interesting, nobody modifies their cars over here, it is always 'bone stock' in boring colours of white or grey.

Sorry I was vague, by "without lights" I meant "without lights turned on and pointing in the direction where they can be seen by other vehicles".

Yes, tubeless bike tires are pretty good wrt of punctures and ride quality, you can maintain them at home but I imagine many people indeed don't bother. Same as many people go to bike shops to replace tubes.

Actually, it's worse in the US due to our regs.
Many European active headlights solutions were banned in the US upon release thanks to the NHTSA. Meanwhile us Europeans got blasted by them daily.
Re: Car headlights don't have to be this blinding
#130This is largely poor regulation. The assumption that "more bright = more safe" and the lack of enough real-world testing. The only other product analogy that comes to mind is "thicker = better" for hiking socks. When they got too thick, they applied too much pressure to the heal and also provided additional moment distance making it far easier to roll an ankle.
I believe that it's more nuanced than that (this is from the context of German regulations): In the old days, reflectors and diffractors were rather crude and light distribution wasn't even at all. Regulation was setting a light intensity limit for the arc above the cutoff, assuming that the brightest spots would be just that, unintended brightness outliers. And when those would comply with the limit, the typical bri…
