While i enjoy the racing, there is one bug that annoys the hell out of me.
In the Brisban race (the longest race in the game) there is one root near the end that seems to have a very bad case of 'sometimes here is an invisible wall and sometimes there isn't' and nothing is more annoying than having 2 minutes of the perfect lap just to have the game decide that now is the time to close the invisible wall on you, so you get stuck and your otherwise perfect run goes down the drain thanks to a bug.
It may be related to the harvestable wood that spawns there, but it doesn't seem to make the difference if you harvest it. If you hit the thing right you get through (and even if you drive against the invisible wall long enough), but if you don't you get stuck and lose all momentum for no explainable reason but a bug.
If you want races to stay fun, please fix this kitten bug.
Here is a screenshot of me rolling against the invisible wall:
