I can think of 2 possibilities.
1: When Optimus Prime's trailer vanishes when he Transforms to Robot mode it actually goes back in time, influencing TF alt-modes to Earth style - hence why all the Autobots have cockpits despite living on a planet with no small lifeforms to drive them. Due to the chronal connection between Orion and Optimus it has an especially strong effect on him, and explains why a genderless robot has a girlfriend to boot.
2: In the same manner as Cybertronians conincidentally speak English like (mostly) 1980s Americans, their pickup trucks also look exactly the same as Earth pickup trucks.

Also, nice one @Sky Shadow.
