That's a tough one. I'm guessing...
Change Lanes even though I've never seen a cockpit version. Pole Position was 1982, Star Wars 1983, and those two games kind of proved that operators would dedicate the real estate for a cockpit. Change Lanes is the only Taito title circa 1982-1983 I can picture having a cockpit version (and a horizontal monitor).
Basically a shot in the dark.
