Yeah, I notice the insight is not low & flat, but rather high & narrow. That didn't help once the roll started.
Also, the aerodynamics for optimizing minimum drag at "regular" speeds probably aren't the best for high speed stability. Getting both at the same time is quite a trick, and I'm sure the design of the Insight was at least 90% for low drag at regular speed, and less than 10% for "high speed stability".
Using that body design for a landspeed attempt makes sense from the standpoint of low drag, but in this case, at least, the high speed stability thing bit him in the ass.....
There's another video out there of a 2nd generation Mazda RX-7 at Bonneville doing much the same thing, but at 210 mph. Same deal - pretty low drag car, but too much lift/instability at high speeds........
