Ernie Prang and Stan Shunpike, the driver and conductor of the Knight Bus, were named after J. K. Rowling's grandfathers, Ernest Arthur Rowling and Stanley George Volant, respectively.1 Ernie's last name is a play on words, as "prang" is English slang meaning "to wreck an automobile". ernie prang
Sadly this info seems to be from a dead article on pottermore, looking for an actual interview to support.
- Ernest Arthur ROWLING was born on 9 July 1916 in Walthamstow, Essex, England and died about 1980 in Newport, Wales.
- Stanley George VOLANT was born on 23 June 1909 in St. Marylebone, London, England.

shunpiker play -ˌpī-kər\ noun
(1) Originally to write off a car through crashing, the term developed in the U.K to mean (2) 'feeling' like a car wreck, specifically mental disassociation through drug (particularly crack, coke and skunk) over-use inducing severe fatigue, unsteadiness, derangement or paranoia. This has evolved to (3) signify any non-specific type of severe fatigue, unsteadiness or apprehension.
So we have both drivers with the names of her grandparents, and both lastnames obvious slang names for some driving related incident.
