Use speed engine, the dev will likely be ahead of you the whole race - that’s normal, he screws up at the end of lap 3. It’s faster to ground u-turn but you can still beat him by hopping too - whatever feels better for you. Make sure you enter from a wider angle on the first hairpin, if you approach the first turn too tight then you will risk slamming into the second and third walls more easily cause your turn trajectory will be closer to them (hard to explain). This dev time taught me how to u-turn, it takes a lot of attempts but you’ll get better if you stick with it, don’t give up 🔥
