It's not the game, but your lack of skills and perseverance that's the issue.
#Higher Tier Ranks Penalised

there are plenty of tracks that do cater to your casual playstyle like most of the beginner tracks. Not to say wanting to play casually is a bad thing by any means. If anything I think there needs to be a casual racing queue that works similar to ranked.
but there are very few tracks where youre primarily flying through the air through obstacles. i.e Airbourne 2, Pleasant Parkway etc.
Most of the sequel tracks give previous tracks a nice touch up and fix areas that make them seem bland and blend in.
I do see your point but no disrespect it also boils down to your skill.

You can always casually race any track that your like privately or with others. The game is called Rocket Racing, and inspiration comes from Rocket League, which is a flying car soccer game. There are many non-flying car racing games. Flying and obstacles are the main feature of the game that differentiates it from others. Saying that its main feature is a problem is like saying that ice cream should be hot or airplanes should travel over roads rather than fly.
