Impressive. Very impressive, Sir.
Regarding height, wind, and handling....
I drove 18-wheelers for 27 years, mostly pulling 53-foot vans, and I was mighty close to blowing over a couple times on I-80 in Wyoming when I had very lightweight Kellogg's cereal loads. But the worst was one time in Oklahoma with the trailer empty -- pretty sure I had daylight under the left trailer tires for a moment.
Millicent, with her two-foot roof raise, has not been in anything like such winds, but I feel I still understand the basics of driving her. And the fundamental concept is that a bus is no more a car than an 18-wheeler is. You simply must
drive a bus as if you are your own grandma. Slow waaaayyyy down for any curve. Never change lanes if you can help it. If a dog runs out in front of you... simply drive right thru it -- don't even twitch a finger on that steering wheel.
By driving Millicent pretty much the way I drove 18-wheelers, I do not expect any difficulty -- even if I raise the roof another foot or so, which I am considering doing. And at the current height we have put 56,950 miles on her so far.
Last year I loaded her past the axle ratings, and the weight was fairly high in the rear cargo compartment. Basically, I had Stuff made of steel stacked to the ceiling. And the living quarters were piled almost as severely -- I had to climb on top of tool chests, lumber, and much else heavy stuff to get to the bathroom midships.
This made for noticeably trickier handling, especially leaning in curves. I drove accordingly -- like great-great-grandma this time.
I don't think I can possibly emphasize enough the importance of driving appropriately for the vehicle and load.
At the trucking company I sometimes trained new drivers, and some of them scared me severely. They had not yet understood what they were driving, and they flew into curves as if they were in a sports car. With a fleet of 200 - 250 trucks, and a severe shortage of experienced drivers, we had one laid over on an exit ramp or other curve about once a month.
I appreciate mathematics. It gets "fun" with wind having increasing leverage for each unit of vehicle-height, and also the diminishing angle to the opposite side tires (as referred to earlier), which increases the tipping force even more. Studying this would no doubt be educational. But what the driver of a tall bus really needs is the realization
that he must use both his gut and his brain every second the bus is in motion.
That concludes the sermon. Please help yourself to cookies and tea in the vestibule.
