First of all, I viscerally dislike driving in general. It makes me pretty anxious, and I generally avoid it if I can. 12 years ago I was driving an old 1984 ford f-150, and I failed to make it completely up an icy hill in the country. I slid back down the hill, from the top of the hill, and went off road at the bottom, with the rear getting chewed apart when it made contact with a stout maple tree.
I also smacked my head on the steel interior truck frame, and had to get stitches there. I think my memory capacity after that, did get slightly poorer
But anecdotes aside, if you google american driving deaths in 2021, the immediate result says 42,915. In contrast I was trying figure out what recent road deaths were in the UK, and it seems to be saying it's something around 1500, which doesn't seem believable, (given proportional comparison to the american rate) but maybe they are dividing up the number in some other way that I am not understanding at a glance.
In any case, the articles I read on this topic of driving danger have seemed to always analyze driver error, and only sparsely include 'structural error.' For example, I can't think of a sound reason why they might create extremely short on-ramps, that enter extremely high-speed roads with no merge lane. Do such things exist in your country?
I've driven mostly in the southwestern U.S., so I've rarely had to deal with driving on icy hills.
The cloverleaf interchanges can be hazardous, as they have short on-ramps and no way to accelerate quickly. However, the newer stretches of road and interchanges seem to be moving away from that to having
longer merge lanes.
As for analyzing driver error over structural error, I've noticed that too. I think it's a combination of both factors, as well as the general practice of using traffic enforcement as a means of gaining revenue or a pretext for harassment - and not a genuine, good-faith commitment to traffic safety. The number of "routine traffic stops" which end in deadly shootings is an indicator of shoddy police practices and corruption at high levels of government. Yet with all the games they play, they're not making society any safer.
I'm not sure how it compares with other countries, but I found a site which compares fatality statistics by state: Fatal Car Accidents by State 2022 (worldpopulationreview.com)
It notes that the lower death rates occurred in the northeastern states, where there is more infrastructure, higher population density, and better mass transit. This also appears to be the case in many European countries with higher population densities than what is typically found in U.S. states.
