Wow I have had a dream very similar quite a few times. I'm driving on some very unstable road, often made of sand and the car falls into the lower levels of that road, getting stuck... Sometimes it's a curvy bridge the car needs to climb and it constantly tends to fall off. I thought the school exams were the only common dreams that I had, but at appears that similar ones to this one is dreamt by others too!

Yeah it’s very surreal, during the dream I realize that hmm, this is pretty dangerous, but am still somehow casual about it, and then I don’t complete the turn and the car starts plummeting down and I start saying I love yous and I wake up

It really sucks lol
