In the end your life / safety is worth more compared to saving a few bucks.I doubt you can ignore vehicle weight for tire design, especially for aquaplaning.
a few hundred kilograms at most
I wonder if modern cars with traction control promote more risky driving because the driver gets less of a hint they're pushing it to the limit before they lose control. Perhaps the car should warn the driver when they're pushing it, by gently vibrating the seat and making a noise?

Golf 4: 1107 kg
Golf 5: 1302 kg
Golf ID3: 1705 kg
Golf ID4: 1966 kg
That's not "a few hundred kilograms at most between comparable cars" but 650 kg.
So the big question is, why are cars getting heavier and more SUV-like all the time, worsening aerodynamics as well? I don't like it. It's also crap on fuel efficiency. This trend affects both ICEs and EVs. And EV designers get some slack from regenerative braking and think they can get away with extra weight, which I don't like either.
...
In addition to that, cars keep getting bigger by about 2cm per year. The latter is due to car manufacturers wanting to sell you a bigger 'the same' car without you thinking you are buying a more expensive model.
...
Ah yes, thank you for reminding me of the other major EV consideration; weight.
So, if someone insists on using normal tyres on their EV, they need to choose a higher load index. Which means stiffer sidewalls, and more road noise. Back to square one... (almost)

Yes, various driver stability improvements promote riskier driving.
When anti-lock brakes first became available there was an opportunity to study their effects on drivers. Some cities required taxi fleets to have anti-lock brakes so there was plenty of good data. Initially the number of collisions went down, but as the drivers became accustomed to anti-lock brakes, the number of collisions increased until it reached the previous level, and on average the collisions became more serious.
The weight figures quoted earlier didn't take the ICE version into account. Meanwhile I found a complete list. A golf 7 with a 1.2 l TSI engine is about 1205 kg. A blue motion version is about 1377 kg and 2.0 TDI weighs 1.366 kg.
It also seems it wasn't honest to compare those numbers with a ID4 because the ID 4 is about 30 cm longer than a golf 7. The difference in weigh between a 2 L TDI and an ID3 is about 300 kg. (with a full fuel tank.)

ID.4 is a baby SUV, compare with something like a Tiguan/Audi Q3/etc.
ID.4 is a baby SUV, compare with something like a Tiguan/Audi Q3/etc.I've been in a Tiguan, and I've been in an ID4. The ID4 seems a lot bigger. I don't think they are comparable. Car sizes are deceptive. We have a Honda Jazz and a Volvo V90. The V90 seems huge compared to the Jazz, yet there is less than a 25% difference in length.

That 25% works out to a meter. If an extra meter gets allocated to the passenger compartment is would seem ocean liner spacious. Even if the passenger compartment doesn't get it all there is plenty for a huge difference in feel. If you are willing to accept another 25% you can get one of our American crew cab behemoths. They do seem extremely roomy inside, even for me and my son (both well over 2 meters tall). Of course finding parking spots, turning around and escaping the fuel pump are all far more difficult. I am willing to be "cramped" into a somewhat smaller vehicle.
