Very cool video, nice work! Obviously this plugin is a professional product especially when combined with Adobe After Effects which isn’t cheap either.
So which buggy were you driving? The difference between the two drivers is pretty dramatic; as the MBX5T is super smooth while the driver of the Robitronic buggy obviously has a heavy finger.
The owner of the mbx5t drove both cars and is obviously more used to the driving behaviour of his mbx5t. The Robitronic Buggy/truggy hybrid is lighter, has a shorter wheelbase and the startup of the Jazz ESC is very sudden making it look more agressive on startup (more easely to wheelie).
The mbx5t is a very predictable and smooth handling car with stock setup. It's way easyer to drive then the Protos buggy/truggy which tends to oversteer.
