As everyone knows -tax dodging cyclists love to cycle the wrong way up one way streets -streets put in by an anti-motorist council to make cycling more "convenient" than driving.
Once these tax-dodgers get used to contraflowing, they end up using those routes even when they drive a car -or in this case, a coach -as seen here in Fishponds.
Before anyone says "how do we know this coach driver is a cyclist?" -the answer is obvious. Only cyclists go the wrong way down one-way streets, so this driver is a cyclist.
