Hi, I've been attempting to beat the IDAP times at time trials, and even though i suck at flyingdespite the fact that TT13 (turbulence - drones (i haven't beaten those yet) flight) has been extremely difficult to beat, i managed to beat TT15 and TT12 without much difficulties.
However, the TT11 (Downhill rumble) cannot be completed with a quick enough time, probably since 2018, because the road between checkpoints 6 and Finish no longer acts as a road, but the cars go only as fast as offroad. In other words, the acceleration above 112 kph is impossible. On the other hand, the road from start until checkpoint 4 acts correctly, and acceleration above 120kph is possible even in a slight uphill climb.
The road once worked correctly, as seen in this video: https://www.youtube.com/watch?v=eESNVHzk2oI&t=105s (1:45), but today, it no longer works (at least since mid 2018, as seen here https://www.youtube.com/watch?v=Gw8D6vHxYCU&t=110s (1:50).
EDIT: the acceleration is bugged even on the first road. The handling revamp present since the TANKS update has broken this time trial, because on the first road (between starting point and checkpoint 2), the guy in the first video managed to accelerate up to 134kph (despite making some mistakes at the start), whereas in the current game version, you are able to hit speeds of 120-121kph, not more.
