Test-drive the car you keep seeing everywhere

There's a car you see ten times a day now — every car park, every junction, suddenly everywhere. Somebody is buying all of them and you have no idea why. A dealership will hand you the keys for twenty minutes, no purchase required — getting you into the driver's seat is the whole business model, and you are, someday, a person who might buy a car. Go in honest, say you're curious about that one, and let the full pitch wash over you. Your job: clock the one feature the salesperson can't stop mentioning, then check whether the car agrees with them.
