I DON'T KNOW IF THIS IS GOING TO HELP IN SPEEDRUNS BUT IT'S KINDA INTERESTING, BECAUSE I WANTED TO DISCOVER IF MONSTER TRUCK IS USEFUL IN CARS PLAYSET AND IT'S I DON'T KNOW BUT BASICALLY IF YOU JUST SPAM A OR D AND SHIFT (OR PROBABLY RIGHT STICK ON THE CONTROLLER) WHILE BEING A MONSTER TRUCK THEN AFTER SOME TIME YOU WILL GET STUCK IN THE GROUND LIKE IN THIS VIDEO: (START FROM 0:04 OR 0:45)

OR IN OTHER CASES YOU WILL DO SOMETHING SIMILAR TO SPEEDBASHING IN CARS 3: DTW LIKE IN THIS VIDEO: (START FROM 0:55 (NOTE: SOMETIMES YOU WILL ALSO FLY INTO THE SKY BUT IT CAN ALSO BE DONE WHILE BEING A CAR))
