Please tell me the RR speed glitch

Hi all,

Can someone please explain the speed glitch to me?

I'm not normally interested in glitches, but I am racing against players (the whole lobbies), every race, that have a base speed substantially higher than mine from the start. It's not fun any more.

There's times I've boosted and they're still going faster than me, on a straight, with them doing no actions other than "hold accelerate and up".

I actually cant finish a race in gold 1 lol (I usually just get to champion then stop with boredom).

It's like a racing F1 cars in a KIA
