Sir, Half-term begins, and once again the traffic jams miraculously disappear. My experience only covers the northern routes into the city, but I imagine that others will support the link between the (private?) school run and Oxford's increasing congestion problems. Do buses serve the four major private schools in North Oxford (Dragon School, Summer Fields, St Edward's School, Oxford High School)? If not, then surely it is time that they did. I imagine that parents enjoy the daily crawl about as much as the rest of us.
