I see that you also updated the demo. Wonderful! It seems that because of my question, you added boxes to the back of a pickup truck. It's nice. By the way, I found a small bug. If the car is turned on the roof and the wheels do not touch the ground, they continue to rotate endlessly, and the speedometer shows about 6-9 km / h, depending on the type of car. In general, physics still looks better compared to most similar assets. Driving sensations remind me Driver 2-3, in which I really liked to just ride around the city. One feels that a lot of effort has been spent on the tire slip model.
