The helmet segment is edited onto that video above. Guilty as charged.
The drive itself is progressive, controlled and the national speed limit reigns on that road. Sure, putting your foot down is always debatable and plenty will argue about their being a time and a place, meaning the track of course. Personally, I would argue against that singular scenario and I would add that the MG video above is a safe, yet spirited drive in all aspects.
The AA, naming the road in the video as one of the top ten drives in the world, supercars on virtually every public road and every McDonalds car park and as much power as you can afford to buy can only surface in one way, speed. Sure, go and get some experience on the track, if you like. It will only serve to make you a safer and more seasoned road user on the public highway. Even whilst driving in a spirited manner.
Most of todays 'standard' cars can do 100mph plus, at the very least, anytime and any place. The percentage of those that have ever used the track is negligible. I have to ask myself why the national speed limit is still only 70mph because you won't get pulled for doing between 80 and 90. Is speed wrong when applied in a car built for it, and by an experienced driver with the ability to apply it correctly? Or, is slow, generally safer on such roads?
