I read or was told at one point as a kid that that was an intentional feature on busses- they made the floor that high on purpose to make them safer for the occupants- instead of a rear collision hitting the frame head on eith their grill, and transferring all that momentum to the occupants, they were hitting the bus with their windshield/ chasis, and, much of the force that did transfer would be pushing the bus up because they were going under it like a wedge
They didn't count on a society so absolutely idiotic that they would make trucks practically as high as a school bus deck legal for people to drive without a special licence and express, present purpose.
You’re assuming a perfectly rigid system. The school bus has a lot of mass in front of the rear wheels and under the hood. But behind the rear wheels, it’s basically just aluminum sheeting bolted onto the frame, and children sitting in seats, packed in like sardines. That means the mass at the front of the bus is actually working against you, because you run the risk of sandwiching all of the kids at the back of the bus. If the tail of a school bus crumples, you’ve just shattered 20 kids’ femurs and the fire department is going to spend the next 6 hours cutting them all out of the wreckage. The ideal method is to direct as much energy away from crumpling the frame as possible. And the best way (aside from adding a cow-catcher wedge to the back of the bus, to fling them off to one side or the other) is by turning it into vertical force that lifts the tail, instead of crumpling directly into it.
The goal of safety design of vehicles is to dissipate as much energy as possible, at no expense to one or the other side.
This is still a rather mild accident of a pasanger vehicle rear-ending a bus. But it's made so much worse simply because of both-sided idiotic vehicle designs.
Most of the world realised that and rectified it rather qucikly.
One car getting under another car is never the "safe" solution.
Are you talking about ideal safety design, or American design IRL?
Because weve been in a weight and height arms-race for decades explicitly because whoever weighs more and is higher is safer, at the expense of the other vehicle.
The cars I'm talking about are far from ideal. Ideal cars would look awful, and since, "for some reason", we're very touchy about what a car should look like, it's a shape of an inefficient, unsafe brick.
But yes, the issue is the arms race, as you've put it. And it's starting to infect Europe as well, so education on vehicle safety is paramount.
Vechicle safety is not "as long as I'm in a tank - I'm safe, and that's all that matters". (This is not aimed at you)

Exactly, would you rather an accident kill a dozen innocent students or 1-2 dumbass(es) who rear ended a bright yellow bus.
Or, you know, kill 0 people, in the normal world.
Edit: only in dumbass america this is a hot take lol
hold on what was the social credit score of the children
None of them have created any shareholder value yet!
This is the normal world.
I have some bad news for you, kid...
It's not that it's a hot take it's just not how things fucking work lol
Yeah, not in the US, that's for sure. You guys think that the solution to gun violence is to shoot before you get shot.

I don’t know, the bus has a lot more mass than most cars - even in a bumper to bumper collision they should come out pretty well

Hey let's explore the cowcatcher idea. Could you design it so the texting rear-enders do a sick barrel roll?
How about A giant ramp so they get launched right over the bus like Evel knievel!
A normal car doesn't have a bumper to bumper collision with a schoolbus. My car would have a bumper-to-headrest collision at that speed.
A bus has a lot of mass in the front, the rest of the bus not so much.

excuse me the multipla looks more like a mangled duck
