I'm not sure the analogy with cars works.I'm going to respond as if you aren't a troll... its a vague of hope of mine to meet a forum of non trolls, but nvm.
I am an ex MoD electronic engineer, I began my career working on communications satellites before moving onto making flying things not.
I admit I am not the most intelligent person I have met in my field, however I have "networked" with Dr Brown and the likes.
Space is "larger" at these altitudes than say, the surface of earth, that's not a hard concept to grasp, farther out on a circle is bigger, even flat earthers can grasp that.
However, the average car crash on earth, (although contested) is less than 30mph. Add in gravity at this level and most debris lands within 12 feet.
The latest incident involving Space X (because its always Elon talked about), happened at approx. 14.4miles ps, or around 52000 Mph.
The ESA sat had to take unilateral action, because SpaceX didn't receive the info due to a "bug". Make of that what you will.
Now add in the 3000 sats that spaceX has, plus added they want (another 4000 was what I heard... pls note I heard). China has 2 "private" operators wanting similar access, India ofc wants theirs, EU is planning on launching another 600 (I have heard more). Russia will want theirs, etc etc.
It is all explained, far more concisely than I can, in Dr Kesslers paper, submitted in 1978. general Wiki https://en.wikipedia.org/wiki/Kessler_syndrome
I cant find the edu link, however I can share it myself https://drive.google.com/file/d/1V3WxucRUZfRQN86tZzW4aRfoMS_-FM-M/view?usp=drive_link
Hopefully anyway.
Cars are driven (almost entirely) by amateurs. By people with the free will to turn, brake or accelerate in any manner and at any time. Often (from my own observations), these movements are without any form of sound reason.
A better analogy would be aircraft. They travel on planned routes at planned speeds at planned times.
There are around 7500-8000 satellites in orbit in an area, as you correctly pointed out, far larger than that of the surface of our planet. It's also 3 dimensional in a way that our roads are not. There are well over a billion cars on the roads. Whilst I'm sure it's not intentional, that kind of analogy could easily be considered to be scaremongering.
I understand the concern with Kessler syndrome but if those collisions were to start due to bad actors or sloppy build/coding then the increase in satellite numbers will barely be a bump on the chart compared to the number of pieces of debris.
StarLink satellites are in low earth orbit - their paths (and that of any debris) decay and will eventually burn up. The plan might be to launch a lot more, but you also have to factor in how many will be removed from orbit in the next few years.
