Did you make sure the parking brake was off? I ended up fixing the cheatbox one and have been using that one and haven't ran into that, I only used this to teleport to the house.At first i was thankful for this mod but soon learned most cars you teleport (like the gifu) will clip and fly off. the satsuma will also on occasion. the van seems to be fine but i think issue with the Gifu is it spawns directly on you and bugs out. thanks for the attempt.
