When I started driving my present coach 5 years ago I kinda worried a little bit that other drivers might think I was a rookie driver burning up my brakes coming down the mountain because my Pacbrake turned on my brake lights. I quickly got over it. Now I don't give a rat's patootie what other drivers think about me or their perceptions of my mountain driving skills.
After a week of classroom and in the seat training to qualify to drive a school bus loaded with "precious cargo" in the Rocky Mountains, yearly retesting and 5 subsequent years experience in all kinds of adverse weather driving any of the 200+ diesel, gas and CNG buses in the fleet in those very mountains IMHO I think I'm pretty good at it. The state designated examiner who administered my CDL Class B driving test told me it was the first time she had given a perfect score on a driving test in her 32 years as a designated examiner.
I wonder how the other drivers who might be critiquing my driving skills would handle the 10% grades on both sides of the Teton Pass in a 33,000# coach hauling a 500# motorcycle on a carrier and a 3,000# car on a tow dolly. The whole rig is 61' long and weighs ~38,000#. BTDT.
I do pay close attention to all the many vehicles without supplementary braking systems screaming downhill past me with brake lights on all the way down hoping the only damage they cause will be to their own clothes and seat cushions.
This explains the way I use my braking systems:
