Well, I can't believe you took it that serious ! First of all, the car was not designed to climb those stairs so just try and imagine all that shock and stress sustained by its suspension and transmission for 999 stairs. That damage perhaps occurs after 100.000 km driven on paved road.
This was done just to show off and pure marketing because most of people are easy to impress and believe everything they see.
It went fast because it had those security lines - how fast would it go without it I wonder ? Not that fast for sure, maybe slower than an old 4x4 vehicle which was designed to reach the impossible and required the driver to have patience and precision: this can go fast, but others can go anywhere - that is the difference.
Your only argument in saving this RR is that it went up those stairs fast with security lines - if they were that sure that their marvelous car is that good - they would have risked it - but they did not.
They wanted to point out that RR is a very good off-road vehicle ( which is partially correct as the older models are used in competitions due to their durability and fiability ) , well imagine that you are around 50 km away from any kind of roads - deep into the jungle/forest/etc and for sure something electric will fail - because we are talking about extreme driving - what they wre trying to point out. What will the car do ? It will stop and it will need special assistance to make it work again ! A real off-road car from the 90s can be fixed in the middle of the jungle without issues - you just need to be a good mechanic, have some skills. The level of discomfort when your expensive SUV can't be used in the middle of the nature and it needs to be towed somewhere to safety will sure be embarrassing.
Have you ever watched a 4x4 competition ? Have you seen that the average age of a car there is at least 15 years old ? You know why ? Because electronic parts fail more often than steel ! Those who do off-road know that !
This RR is a car for normal roads and unpaved roads - but it is not what they advertised it to be, that is what concerns me ! False advertising !
I have a Suzuki Samurai from 1988 and people laugh at it being small and so on, but when they got stuck with their Touaregs and Mitsubishi L200 in the mud, I just mind my journey.
What I want to point out is that the only reliable off-road cars that are being produced today are the Mercedes G-Class - even though it started being full of electronics, the Land Rover Defender and Jeep Wrangler. And if you want real off-road vehicle you have to choose something from 1970-1995 at maximum.
Why do you think a Mercedes G Class from 1995 is around 15.000 euros on sale ? Because it has won its name as a reliable and durable vehicle. That kind of vehicles are not made today anymore.
And this is a real-life example :

This is what the old-man said :
In a modern car, he insists, this would not have been the case, for one reason – computers. Otto was built in 1988, a couple of years before cars started going electronic.
“Otto is nothing but nuts and bolts that means I can unscrew the nuts and pull out bolts to repair anything that comes up myself,” he said in 2013. “In any modern car you cannot touch the brakes because it’s all electronically controlled.”
As for the Hummer - the H1 was a hit - I can agree , but H2 is just a big bull that has no purpose.
