Jim Parsons is somewhat different to Sheldon.
Jim Parsons’ character Sheldon can’t drive so he spends a lot of time bugging his friends to drive him around. In real life, however, Parsons gets motion sickness when he rides cars so he actually prefers to be the driver. Ah, just another stark difference between an actor and the character he plays on television. (Did we mention he’s also gay in real life? Yep.)
