Justin, turned around to Sally. "Come on. It isn't that bad. Come here." Justin forced his hand to wrap around her own, as he took it hostage for a moment to pull her over to his car. Once he was standing just in front of it, he dropped his grip; which allowed her to take her hand back, if she wanted to.
"Okay, something you need to know about cars is -- well they're probably more safe than broomsticks." Well he didn't have any facts on that, but last time he had been on a broom, he ended up with a burst appendix. Arguably they probably weren't connected. "I'm a really good driver. You seriously have nothing to worry about."
Justin, pulled open the right hand door for her and once she was sitting inside, walked over to his own side and hoped in. "Maybe, I should give you a lesson one day. Conquer your fears and everything?" His smiled disappeared when he noticed Sally wasn't wearing her seatbelt, though. He leaned over, gave her a smile; so she didn't think he was going to pull anything (or perhaps that just convinced her further - he wasn't a mind reader) and pulled the seatbelt over her, before he buckled it up. "See. Now you are safe. Music? I think, I've got some Bach in here."
