Normally I would agree with you, but I don't think you have ever driven a Prius. These cars are in a class all by themselves. The gear shift is not mechanical. It is 100% electronic, so if things ain't workin' right, then you are at the mercy of what Mr. Prius feels like doing. Don't get me wrong, the Prius is a very cool car. I have driven one on a few occasions, but there is a reason why they have the highest insurance costs. You know, if you look on eBay and Craigslist, at least 50% of the Prius' for sale have a salvaged title. Like a motorcycle or a commercial vehicle, this vehicle should require a special endorsement before people are legally able to drive this vehicle. For starters, the vehicle does not have a "Park" gear...only neutral. Countless people have put this vehicle in "Park", only to get out of their vehicle and watch their Prius roll away.
Was he acting? Maybe, but he didn't look like a stupid guy, and I think with all of the attention that he knew this was going to get, he knew the truth will come out. What would he stand to gain by lieing? Unless he is lobbying for a reality TV show, I don't think the benefits outweigh the risks. Everyone still remembers the trouble Richard Heene got into.
All of that being said, I think the guy who had the problem recently had a real problem. A CHP saw the vehicle's brake's a smokin', and saw the man standing completely on his brakes. I think the guy did a great job of getting it stopped, and that it took a lot of strength and weight. If that had been a woman, there would probably be a lot of people in mourning today.
