They will, entertainingly, try to sell you train tickets even if the airport doesn't have a train station.
They also send _constant_ emails about car rental (I assume it must be a profit centre for them). Yes, Ryanair, I will definitely want to rent a car for my weekend trip to notoriously-car-friendly _London_.
Better, yes. More convenient, no. That's why Bookingcom offers to load you with a rental car, train ticket and god knows what else, why Ryanair offers train tickets and why hotels do the same - massively reduced friction.
