Cheating in Rocket Racing?

I have noticed in rocket racing, specifically casual racing, there are people who have an unreasonably high amount of speed all the time. for example, everyone knows the drift left then right trick for straight lines to get more boost speed, theres some people who are doing that constantly throughout entire courses in casual who arent releasing their drift at all, and are consistently going 900+ kph. nearly impossible to catch up to them, and when they arent drifting while going 900 kph, they’re using their boosts. so basically i am asking: has anyone else seen this in casual? im a well seasoned racing player, i saw unreal ranked matched last year when it started, and elite this season, and i havent seen anything like that in ranked racing.
