Haha, I suppose that record is mine (oh I couldn't post the screenshot as I got an error)
But let's get professional here :P
Theme:
Probably it will be the hardest part to rate as I couldn't get far enough to feel the influence between distance, fuel, speed etc. I assume that if game was a bit easier to play, it would be much more visible with time progression, but as I said it's really hard for me to rate how well you did there.
Visuals:
Actually I liked that part. Maybe car model was outsourced, but never the less you made an attempt to create environment yourself and what's even more important, you tried on creating interaction between art and gameplay (and that is impressive!). So first of all. Your idea with menu was incredible. I love myself making games where already in menu you learn the mechanics of the game and not just click the button, that was really great! (Would be great if you disabled crosshair as it's not really important in the game and it takes some attention). Same with trees in actual game. Use of them as obstacles is really wise choice, however you would need to place them a bit more carefully, as road was not possible to cross at some point.
As for tree's visuals it's a bit unclear what is their shape so it was pretty hard to manouver around them, maybe it would be good to change style for something more clear like lowpoly (https://3dwarehouse.sketchup.com/warehouse/v1.0/publiccontent/c343204c-de19-41a2...). It should be easy to model (there are tutorials on YT) and it would be much easier to place them well.
Also in art consistensy is really important. When you play a game where 1 object is significantly better made than others, you start to see mistakes, if you want your game to look good, you don't really need high quality graphics. Game will look well if all the aspects of the game are made in a similar style (good example is Undertale or Minecraft. Art made in these games is not really 'professional' but they are consistent, minecraft uses blocks shapes for everything, blocks, sun, particles on hit, animals etc. If water in minecraft looked hyperrealistic it wouldn't fit the game). So it's really important to think about details like models, skybox, road (if you could find some texture to put on it, it might make this already much better).
As for UI. They things you've indicated were good. There wasn't too much information and was easily readable. Maybe you could use more of images UI (there are many minimalistic UI on asset store etc). People usually prefer to not be overwhelmed by text, so if you could replace it with symbols, it would be much more pleasurable). And remember about consistency, UI also must fit the game (good example is 'Totally Accurate Battle Simulator': where game itself is minimalistic and so is UI).
Innovation:
There are many games that are race games on some air-placed roads, so if you were to upgrade this game in the future, you can think about making it more unique at some point. Maybe you can use the bugs that you have (bugs don't need to be a problem, 'Goat Simulator' or 'Team Fortress 2' is a great example. So maybe you can even enhance on that. Put some bouncy material on the car or sth, to make ragdolls even more crazy, or things like that). Just a loose idea, but think of what game you would like to have/play and try to aim in that direction.
Gameplay:
I'm actually very impressed with the controls, they are really smooth ( I have no idea how you did it), but I also have no idea what is the connection of the car and the road, but clearly there is xD
I think it would be better to make car independent of the road, so that it can fell easily, it wouldn't feel so weird while driving. Apart from that it's good to plan gameplay the way it's enjoyable for everyone, so you start easy and then it progressively starts to get harder and harder. You have placed many curves really close to the beginning of the game and it was really hard to get further in the game (as developers it's always hard to measure the difficulty of the game, as you playtest it a lot and become good at it, so always try to make game a bit easier than you suppose it should).
SFX:
Sounds were good, same for music. It went well with the atmosphere of the game and was very enjoyable :)
Game Design:
One of the main principles of Game Design is to make game a whole (a continuous story). When you stop the music and give player a wall of text after entering Play or Credits, it really throws you our of game atmosphere, you should really avoid that. Keep music continuous, if you want to change it then fade in and fade out so that it doesn't hurt your ears. Same with game itself. People usually don't like to read in games, especially walls of texts. Choose only most relevant information and it's best if you try to teach it player in gameplay itself, like you did with menu (you learn gameplay by driving the car in menu), so instead of giving people texts, maybe you can indicate somehow (arrow, outline or anything like that) that player should collect those fuels etc. You can watch Game Maker's Tool Kit and see some references in other games, as it's really good to notice how they attract the player.
Overall:
Oh it was kinda long :P Hope it's helpful somehow.
Thanks for making this game, I had a lot of fun in it (some bugs made it really enjoyable :D) and I'm looking forward to seeing more from you!
