it all depends on how many times the other car across from you that shoots the red light on your car that it will spin cause when I ride it I like to shoot the red light on it to see how many times I can make the other car spin
I have a very hard time with spinning rides (inner ear issues). Having said that I love MIB! I don't think it spins all that much. I just don't keep going on one ride after another. I try to hit it in the morning and then again later in the day.
No. It's part of the ride--your car and their car appear infected with aliens, so you're told to shoot at their exhaust port. Doing so will cause you/them to spin around. It's also a HUGE point gaining target.
I too am not a big fan of the spinning rides but one trick that I have learned over the years is to close my eyes as the car is about to start spinning. This keeps the butterflies at bay and also keeps you more alert to build up your score while everyone else gets their bearings.
