I've found that good camera views are the key to difference in whether you can enjoy driving a bus, or not. Take the recent Sobol NEOMAN release - the camera views in that changed depth way too often, and it gave for a very odd driving experience. It's the absolute first thing I do after downloading any new bus.
Another thing you might like - bare with it though as I've got to run-down it so you understand:
I have Square and Circle set to left and right camera pan on my steering wheel
I've also assigned Ctrl+Left Arrow and Ctrl+Right Arrow as camera pans
In my cab camera views, I've set [view_ticketselling] to 'look full left' and [view_schedule] to 'look full right'. I've assigned both respectively to my keyboard to Left Arrow and Right Arrow (no Ctrl) - so when I'm at a junction and need to quick glance left and right for traffic, I can do so easily without going "...click click... Balls ...click click click... Jesus UGH ...click click click click..."
It's handy!
