I went to see it the day it came out in theaters. The theme is that
the bus looses its clutch, and they have to keep it between 3rd and
4th gear. So, everytime they stop they park it on a hill or push it up
to speed, and start it in 3rd. On the way home, i lost 1st gear and
was also unable to stop. Watch closely, their constantly being passed
by faster traffic. I love that aspect of it.
