It's pretty easy to steal a bus. The driver often steps off the bus and leaves it running. It's really not the stealing part that hard, it's the driving part. I mean sure, straight line is pretty easy. A lot of the busses are automatics so you don't even have to shift. But really when you have police on your ass and you have a busfull of screaming casino goers and plus your cohorts are firing shots out the back blown out window and one shooting out the open side door and you have a blown outside rear tire and the sirens, I mean fuck! The sirens are so fucking loud when they are that close! Plus there is like eight of them and the bus feels like it's gonna roll right the fuck over every corner and it's worse when you curb it. On the up side, it's not like anyone is gonna run a bus off the road and with all the old people on board no one is shooting back and so you sideswipe a car or sixteen, big deal.
So, I guess what I'm saying is that it's easy but the get away is a bit tough. Prepare for some serious time.
