But if the car was locked, as it was supposed to be (or else why would W1 default to it was locked when asked by LE) how did the money get stolen? I'm starting to think maybe his relationship with the S family was starting to sour - maybe SS started to pick up on his lies/shady behavior and was planning to fire him. Or maybe SS wasn't providing W1 with enough attention money for HIS racing, and he started to feel like the pit crew for a ten year-old, which was not why he was nice to the kid to begin with. I think he was nice to PS to gain the trust of SS, but it was all an act to get to his money, either as a sponsor or as a mark. When SS realized he had invited a viper into his midst, he realized he needed to get rid of him. Now Mr. Wanna-be-race-car-driver has NOBODY to support his race-car dreams - no AutoBahn, no BRC profits, no sponsors, no SS - and he has races coming up in Italy or wherever.
I think this guy is a pathological liar and a psychopath (they are often very charming). He doesn't seem to be able to maintain relationships (since it's always all about him) so he runs through people pretty quickly. The photo-posting on SM put the whole family at risk. If AS found out about it, I'm pretty sure she would want him away from her family. It just feels icky - like an invasion of privacy - that he posted photos of their stuff.
