I had the same reaction for a split second--remember that I mentioned I raced motorcycles on road circuits, well when you head turned what was going through my head was "oh frack, here comes a wicked highside" as it truly did look like you hit a patch of oil or your rear tire had a super sudden deflation and came off the tire, causing the rear to snap around. I watch a lot of motorcycle racing on tv and I forgot that your camera view was with your helmet.....

as for the road, we all sometimes "let er go" on downhills, but that particular one with the driveways and hedges would make my little voice say....nope, keep it down. Remember James Dean eh? (he got killed by an Uncle or Grampa Joe type pulling out in front of Dean's low, silver, non-speeding Porsche simply cuz he didnt look properly) and we all know folks that a lot of the time we are pretty invisible to folks in a rush or distracted in cars....
