Businessman (Gridlock)
From Tardis Wiki, the free Doctor Who reference
A dapper businessman was on the New New York motorway when the Tenth Doctor fell onto his vehicle. He offered the Doctor a drink when the Doctor was choking from the fumes in the Motorway. When the Doctor opened the air vents, he opened the lower escape hatch on his car; as they looked beneath the fast lane, instead of seeing an empty lane they saw hordes of Macra, ready to snap at the annoying cars above them. The escape hatch above them then opened and the Doctor was reunited with Catkind Novice Hame, who immediately teleported away with him. The businessman later got out off the gridlock through the roof of the Motorway. (DW: Gridlock)
