It's a decent offer, but he could walk along Freshbrook Road - it's not that far, although the pavement could cause an ankle injury if he's not careful.
He'd have to park the car first, or get a cab to Chichester station as well - I don't think his house is within walking distance. Or he could get a foldable bike for the train - probably the best thing to do.
But he'd love the view at the Fontwell roundabout. Be a shame if he tried to cut through at Poling and realised too late that it was a no through road - may well add 10 mins to the journey.
