Can someone explains how this happens?

as title. thank you !

Driver didn't brake but lifted off throttle giving "lift off oversteer", didn't catch it and recover because they should have given a little throttle to straighten it, ended up touching the curb at the wrong angle and wrong time and that's how it happened.

Idiot turned his car at almost 90 degrees to the direction of travel at high speed by lifting the throttle and then flipped his car. Didn't help that his left front tyre was also touching the kerb, probably making it worse.

turn in>lose traction>drift>regain traction at the same time launching off the curb>car flips>slide>into sand trap> digs in and flips back onto 4 tyres.

very stiff suspension + big bump = catastrophic weight shifting and bye bye.

Lucky he didnt hit the armco its a stupid price to replace per meter lol

FWD rule 1: Don't lift off the throttle or brake while the steering wheel isn't straight; and if you do, make sure you're ready to push it right back into the floor because you're about to meet your tail. The faster you are going, the more important this is.

i guess any sudden movement in high speed is very danger...

when do ppl learn how to drive...

At any speed sudden changes are not good. Fast driving is smooth driving.
Professional drivers make mistakes sometimes too - this guy got unlucky. You can bet he has learned his lesson.

rear tyre lifting is a common problem with the ep3 and the dc5 type R, atleast thats what i read.
