I drove school buses once upon a time. The bigger diesel buses (no hood on the front) will carry 85 kids and go about 300 miles on a tank IIRC. The smaller ones should hold at least 40 people and go much farther than 100 miles on a tank. Even if only 100 miles, it would get people out of the worst areas.
Interesting. Thank you for sharing your first hand knowledge.
In your judgement, given that all of the blanco buses pictured here have hoods, would you say they have a capacity of around 40 ?
