One last time....running your personal vehicle into a stationary tank will not give the driver bad sport. This is why if I'm in my tank I don't move.
What? That's not how it works, especially for personal tanks. Even if you get out of the tank and run 100 feet away from it, you'll still get Bad Sport if anyone crashes their vehicles into it.
The same way you still get punished for driving someone's PV into the water even if you jump out first, a personal tank acts as if the previous driver is still inside of it even if they run away on foot.
